Zupanc, Abstract We report on new flavor tagging algorithms developed to determine the quark-flavor content of bottom ("Image missing") mesons at Belle II. The algorithms provide essential inputs for measurements of quark-flavor mixing and charge-parity violation. We validate and evaluate the performance of the algorithms using hadronic "Image missing" decays with flavor-specific final states reconstructed in a data set corresponding to an integrated luminosity of 62.8 fb$$^{-1}$$, collected at the "Equation missing" resonance with the Belle II detector at the SuperKEKB collider. We measure the total effective tagging efficiency to be $$\begin{aligned} \varepsilon _\mathrm{eff} = \big (30.0 \pm 1.2(\text {stat}) \pm 0.4(\text {syst})\big )\% \end{aligned}$$for a category-based algorithm and $$\begin{aligned} \varepsilon _\mathrm{eff} = \big (28.8 \pm 1.2(\text {stat}) \pm 0.4(\text {syst})\big )\% \end{aligned}$$for a deep-learning-based algorithm., 2022年04月, 82, 4, 研究論文（学術雑誌）

Zhukova, We present a search for the decays of B-0 mesons into a final state containing a Lambda baryon and missing energy. These results are obtained from a 711 fb(-1) data sample that contains 772 x 10(6) B (B) over bar pairs and was collected near the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We use events in which one B meson is fully reconstructed in a hadronic decay mode and require the remainder of the event to consist of only a single A. No evidence for these decays is found, and we set 90% confidence level upper limits on the branching fractions in the range 2.1-3.8 x 10(-5). This measurement provides the world's most restrictive limits, with implications for baryogenesis and dark matter production., 2022年03月04日, 105, 5, 研究論文（学術雑誌）

A significant $$ {\Lambda}_c^{+} $$→ pη′ signal is observed for the first time with a signal significance of 5.4σ. The relative branching fraction with respect to the normalization mode $$ {\Lambda}_c^{+} $$→ pK⁻π⁺ is measured to be$$ \frac{\mathcal{B}\left({\Lambda}_c^{+}\to p\eta^{\prime}\right)},{\mathcal{B}\left({\Lambda}_c^{+}\to {pK}^{-},{\pi}^{+}\right)}=\left(7.54\pm 1.32\pm 0.73\right)\times {10}^{-3}, $$ where the uncertainties are statistical and systematic, respectively. Using the world-average value of $$ \mathcal{B}\left({\Lambda}_c^{+}\to {pK}^{-},{\pi}^{+}\right) $$ = (6.28 ± 0.32) × 10⁻², we obtain$$ \mathcal{B}\left({\Lambda}_c^{+}\to p\eta^{\prime}\right)=\left(4.73\pm 0.82\pm 0.46\pm 0.24\right)\times {10}^{-4}, $$ where the uncertainties are statistical, systematic, and from $$ \mathcal{B}\left({\Lambda}_c^{+}\to {pK}^{-},{\pi}^{+}\right) $$, respectively., 2022年03月, 2022, 3, 研究論文（学術雑誌）

Zhukova, We search for a light Higgs boson (A(0)) decaying into a tau(+)tau(-) or mu(+)mu(-) pair in the radiative decays of Upsilon(1S). The production of Upsilon(1S) mesons is tagged by Upsilon(2S) -> pi(+)pi(-)Upsilon(1S) transitions, using 158 x 10(6) Upsilon(2S) events accumulated with the Belle detector at the KEKB asymmetric energy electron-positron collider. No significant A(0) signals in the mass range from the tau(+)tau(-) or mu(+)mu(-) threshold to 9.2 GeV/c(2) are observed. We set the upper limits at 90% credibility level (C.L.) on the product branching fractions for Upsilon(1S) -> gamma A(0) and A(0) -> tau(+)tau(-) varying from 3.8 x 10(-6) to 1.5 x 10(-4). Our results represent an approximately twofold improvement on the current world best upper limits for the Upsilon(1S) -> gamma A(0) (tau(+)tau(-)) production. For A(0) -> mu(+) mu(-), the upper limits on the product branching fractions for Upsilon(1S) -> gamma A(0) and A(0) -> mu(+)mu(-) are at the same level as the world average limits, and vary from 3.1 x 10(-7) to 1.6 x 10(-5). The upper limits at 90% credibility level on the Yukawa coupling f((SIC)(1S)) and mixing angle sin theta(A0) are also given., 2022年02月23日, 128, 8, 研究論文（学術雑誌）

Zhukova, Abstract We present a measurement of the Cabibbo-Kobayashi-Maskawa unitarity triangle angle ϕ₃ (also known as γ) using a model-independent Dalitz plot analysis of B⁺ → D ($$ {K}_S^0 $$h⁺h⁻)h⁺, where D is either a D⁰ or $$ \overline{D} $$⁰ meson and h is either a π or K. This is the first measurement that simultaneously uses Belle and Belle II data, combining samples corresponding to integrated luminosities of 711 fb⁻¹ and 128 fb⁻¹, respectively. All data were accumulated from energy-asymmetric e⁺e⁻ collisions at a centre-of-mass energy corresponding to the mass of the Υ(4S) resonance. We measure ϕ₃ = (78.4 ± 11.4 ± 0.5 ± 1.0)°, where the first uncertainty is statistical, the second is the experimental systematic uncertainty and the third is from the uncertainties on external measurements of the D-decay strong-phase parameters., 2022年02月, 2022, 2, 研究論文（学術雑誌）

Zhukova, We present a measurement of the branching fractions of the Cabibbo favored (B) over bar (0) -> D+pi(-) and the Cabibbo suppressed (B) over bar (0) -> D+K- decays. We find B((B) over bar (0) -> D+pi(-)) = (2.48 +/- 0.01 +/- 0.09 +/- 0.04) x 10(-3) and B((B) over bar (0) -> D+K-) = (2.03 +/- 0.05 +/- 0.07 +/- 0.03) x 10(-4) decays, where the first uncertainty is statistical, the second is systematic, and the third uncertainty is due to the D+ -> K-pi(+)pi(+) branching fraction. The ratio of branching fractions of (B) over bar (0) -> D+K- and (B) over bar (0) -> D+pi(-) is measured to be R-D = [8.19 +/- 0.20(stat) +/- 0.23(syst)] x 10(-2). These measurements are performed using the full Belle dataset, which corresponds to 772 x 10(6) B (B) over bar pairs and use the Belle II software framework for data analysis., 2022年01月11日, 105, 1, 研究論文（学術雑誌）

Tagging is accomplished through a partial reconstruction of semileptonic decays B-s -> D(s)Xl nu, where X denotes unreconstructed additional hadrons or photons and l is an electron or muon. With 121.4 fb(-1) of data collected at the gamma(5S) resonance by the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider, we obtain B(B-s -> DsX) = (60.2 +/- 5.8 +/- 2.3)%, where the first uncertainty is statistical and the second is systematic., 2022年01月11日, 105, 1, 研究論文（学術雑誌）

Zhukova, Using the entire data sample of 980 fb(-1) collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider, we present measurements of the branching fractions of the Cabibbo-favored decays Xi c(0) -> Lambda K-S(0), Xi(0)(c) ->Sigma K-0(S)0, and Xi c(0) -> Sigma K-+(-). Taking the decay Xi c(0) -> Xi(-)pi(+) as the normalization mode, we measure the branching fraction ratio B(Xi(0)(c) -> Lambda K-S(0))=B(Xi(0)(c) -> Xi(-)pi(+)) = 0.229 + 0.008 + 0.012 with improved precision, and measure the branching fraction ratios B(Xi 0c -> Sigma K-0(S)0)=B(Xi(0)(c) -> Xi(-)pi(+)) = 0.038 + 0.006 + 0.004 and B(Xi(0)(c) -> Sigma K-+(-))=B(Xi(0)(c) -> Xi(-)pi(+)) = 0.123 + 0.007 + 0.010 for the first time. Taking into account the branching fraction of the normalization mode, the absolute branching fractions are determined to be B(Xi(0)(c) -> Lambda K-S(0)) = (3.27 + 0.11 + 0.17 + 0.73) x 10(-3), B(Xi(0)(c) -> Sigma K-0(S)0) = (0.54 + 0.09 + 0.06 +0.12) x 10(-3), and B(Xi(0)(c) -> Sigma K-+(-)) = (1.76 + 0.10 + 0.14 + 0.39) x 10(-3). The first and second uncer-tainties above are statistical and systematic, respectively, while the third ones arise from the uncertainty of the branching fraction of Xi(0)(c) -> Xi(-)pi(+)., 2022年01月06日, 105, 1, 研究論文（学術雑誌）

Zhukova, We present the measurement of the first to fourth order moments of the four-momentum transfer squared, q(2), of inclusive B -> X(c)l(+)upsilon(l) decays using the full Belle dataset of 711 fb(-1) of integrated luminosity at the gamma(4S) resonance where l = e, mu. The determination of these moments and their systematic uncertainties open new pathways to determine the absolute value of the Cabibbo-Kobayashi-Maskawa matrix element V (cb) using a reduced set of matrix elements of the heavy quark expansion. In order to identify and reconstruct the X-c system, we reconstruct one of the two B-mesons using machine learning techniques in fully hadronic decay modes. The moments are measured with progressively increasing threshold selections on q(2) starting with a lower value of 3.0 GeV2 in steps of 0.5 GeV2 up to a value of 10.0 GeV2. The measured moments are further unfolded, correcting for reconstruction and selection effects as well as QED final state radiation. We report the moments separately for electron and muon final states and observe no lepton flavor universality violating effects., 2021年12月30日, 104, 11, 研究論文（学術雑誌）

Zhukova, The first measurements of differential branching fractions of inclusive semileptonic B -> X(u)l(+)v(l) decays are performed using the full Belle data set of 711 fb(-1) of integrated luminosity at the gamma(4S) resonance and for l = e, mu. With the availability of these measurements, new avenues for future shape-function modelindependent determinations of the Cabibbo-Kobayashi-Maskawa matrix element vertical bar V-ub vertical bar, can be pursued to gain new insights in the existing tension with respect to exclusive determinations. The differential branching fractions are reported as a function of the lepton energy, the four-momentum-transfer squared, light-cone momenta, the hadronic mass, and the hadronic mass squared. They are obtained by subtracting the backgrounds from semileptonic B -> X(c)l(+)v(l), decays and other processes, and corrected for resolution and acceptance effects., 2021年12月22日, 127, 26, 研究論文（学術雑誌）

We also set the upper limit on the cross section of the process e(+)e(-) -> Upsilon(1S)eta to be sigma(e(+)e(-) -> Upsilon(1S)eta') < 0.037 pb at 90% C.L.

The results, (tau)(D-0) = 410.5 +/- 1.1 (stat) +/- 0.8(syst) fs and tau(D-0) = 1030.4 +/- 4.7 (stat) +/- 3.1 (syst) fs, are the most precise to date and are consistent with previous determinations., 2021年11月19日, 127, 21, 研究論文（学術雑誌）

Zhukova, A search for the flavor-changing neutral-current decay B^{+}→K^{+}νν[over ¯] is performed at the Belle II experiment at the SuperKEKB asymmetric energy electron-positron collider. The data sample corresponds to an integrated luminosity of 63  fb^{-1} collected at the ϒ(4S) resonance and a sample of 9  fb^{-1} collected at an energy 60 MeV below the resonance. Because the measurable decay signature involves only a single charged kaon, a novel measurement approach is used that exploits not only the properties of the B^{+}→K^{+}νν[over ¯] decay, but also the inclusive properties of the other B meson in the ϒ(4S)→BB[over ¯] event, to suppress the background from other B meson decays and light-quark pair production. This inclusive tagging approach offers a higher signal efficiency compared to previous searches. No significant signal is observed. An upper limit on the branching fraction of B^{+}→K^{+}νν[over ¯] of 4.1×10^{-5} is set at the 90% confidence level., 2021年10月27日, 127, 18, 181802, 181802, 研究論文（学術雑誌）, 国際誌

We obtain$$ {\displaystyle \begin{array},{c}\mathcal{B}\left({D}^0\to {\pi}^{+},{\pi}^{-}\eta \right)=\left[1.22\pm 0.02\left(\mathrm{stat}\right)\pm 0.02\left(\mathrm{syst}\right)\pm 0.03\left({\mathcal{B } }_{\mathrm{ref } }\right)\right]\times {10}^{-3},\\ {}\mathcal{B}\left({D}^0\to {K}^{+},{K}^{-}\eta \right)=\left[{1.80}_{-0.06}^{+0.07}\left(\mathrm{stat}\right)\pm 0.04\left(\mathrm{syst}\right)\pm 0.05\left({\mathcal{B } }_{\mathrm{ref } }\right)\right]\times {10}^{-4},\\ {}\mathcal{B}\left({D}^0\to \phi \eta \right)=\left[1.84\pm 0.09\left(\mathrm{stat}\right)\pm 0.06\left(\mathrm{syst}\right)\pm 0.05\left({\mathcal{B } }_{\mathrm{ref } }\right)\right]\times {10}^{-4},\end{array } } $$ where the third uncertainty ($$ \mathcal{B} $$_ref) is from the uncertainty in the branching fraction of the reference mode D⁰ → K⁻π⁺η. The color-suppressed decay D⁰ → ϕη is observed for the first time, with very high significance. The results for the CP asymmetries are$$ {\displaystyle \begin{array},{c},{A}_{CP}\left({D}^0\ {\pi}^{+},{\pi}^{-}\eta \right)=\left[0.9\pm 1.2\left(\mathrm{stat}\right)\pm 0.5\left(\mathrm{syst}\right)\right]\%,\\ {},{A}_{CP}\left({D}^0\to {K}^{+},{K}^{-}\eta \right)=\left[-1.4\pm 3.3\left(\mathrm{stat}\right)\pm 1.1\left(\mathrm{syst}\right)\right]\%,\\ {} ACP\ \left({D}^0\to \phi \eta \right)=\left[-1.9\pm 4.4\left(\mathrm{stat}\right)\pm 0.6\left(\mathrm{syst}\right)\right]\%.\end{array } } $$ The results for D⁰ → π⁺π⁻η are a significant improvement over previous results. The branching fraction and A_CP results for D⁰ → K⁺K⁻η, and the ACP result for D⁰ → ϕη, are the first such measurements. No evidence for CP violation is found in any of these decays., 2021年09月, 2021, 9, 研究論文（学術雑誌）

Zhulanov, We present measurements of partial branching fractions of inclusive semileptonic B→Xuℓ+νℓ decays using the full Belle dataset of 711 fb-1 of integrated luminosity at the ϒ(4S) resonance and for ℓ=e, μ. Inclusive semileptonic B→Xuℓ+νℓ decays are Cabibbo-Kobayashi-Maskawa (CKM) suppressed and measurements are complicated by the large background from CKM favored B→Xcℓ+νℓ transitions, which have a similar signature. Using machine learning techniques, we reduce this and other backgrounds effectively, while retaining access to a large fraction of the B→Xuℓ+νℓ phase space and high signal efficiency. We measure partial branching fractions in three phase-space regions covering about 31% to 86% of the accessible B→Xuℓ+νℓ phase space. The most inclusive measurement corresponds to the phase space with lepton energies of EℓB>1 GeV, and we obtain ΔB(B→Xuℓ+νℓ)=(1.59±0.07±0.16)×10-3 from a two-dimensional fit of the hadronic mass spectrum and the four-momentum-transfer squared distribution, with the uncertainties denoting the statistical and systematic error. We find |Vub|=(4.10±0.09±0.22±0.15)×10-3 from an average of four calculations for the partial decay rate with the third uncertainty denoting the average theory error. This value is higher but compatible with the determination from exclusive semileptonic decays within 1.3 standard deviations. In addition, we report charmless inclusive partial branching fractions separately for B+ and B0 mesons as well as for electron and muon final states. No isospin breaking or lepton flavor universality violating effects are observed., 2021年07月12日, 104, 1, 研究論文（学術雑誌）

Zhukova, We report the measurement of branching fractions and CP-violation asymmetries in B→φφK decays based on a 711 fb-1 data sample containing 772×106 BB¯ events. The data were recorded at the I(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. For B+→φφK+, the branching fraction and CP-violation asymmetry measured below the ηc threshold (mφφ<2.85 GeV/c2) are [3.43-0.46+0.48(stat)±0.22(syst)]×10-6 and -0.02±0.11(stat)±0.01(syst), respectively. Similarly, the branching fraction obtained for B0→φφK0 below the ηc threshold is [3.02-0.66+0.75(stat)±0.20(syst)]×10-6. We also measure the CP-violation asymmetry for B+→φφK+ within the ηc region (mφφ[2.94,3.02] GeV/c2) to be +0.12±0.12(stat)±0.01(syst)., 2021年03月29日, 103, 5, 研究論文（学術雑誌）

The obtained mixing-induced and direct CP asymmetries are -0.71±0.23 (stat)±0.05 (syst) and 0.12±0.16 (stat)±0.05 (syst), respectively. These values are consistent with the Standard Model predictions. The significance of CP violation differs from zero by 2.5 standard deviations., 2021年02月08日, 103, 3, 研究論文（学術雑誌）

Yuan; Y. Yusa; Z. P. Zhang; V. Zhilich; V. Zhukova; V. Zhulanov, We present the results of the first Dalitz plot analysis of the decay D0→K-π+η. The analysis is performed on a data set corresponding to an integrated luminosity of 953 fb-1 collected by the Belle detector at the asymmetric-energy e+e- KEKB collider. The Dalitz plot is well described by a combination of the six resonant decay channels K̄∗(892)0η, K-a0(980)+, K-a2(1320)+, K̄∗(1410)0η, K∗(1680)-π+ and K2∗(1980)-π+, together with Kπ and Kη S-wave components. The decays K∗(1680)-→K-η and K2∗(1980)-→K-η are observed for the first time. We measure ratio of the branching fractions, B(D0→K-π+η)B(D0→K-π+)=0.500±0.002(stat)±0.020(syst)±0.003(BPDG). Using the Dalitz fit result, the ratio B(K∗(1680)→Kη)B(K∗(1680)→Kπ) is measured to be 0.11±0.02(stat)-0.04+0.06(syst)±0.04(BPDG); this is much lower than the theoretical expectations (≈1) made under the assumption that K∗(1680) is a pure 13D1 state. The product branching fraction B(D0→[K2∗(1980)-→K-η]π+)=(2.2-1.9+1.7)×10-4 is determined. In addition, the πη′ contribution to the a0(980)± resonance shape is confirmed with 10.1σ statistical significance using the three-channel Flatté model. We also measure B(D0→K̄∗(892)0η)=(1.41-0.12+0.13)%. This is consistent with, and more precise than, the current world average (1.02±0.30)%, deviates with a significance of more than 3σ from the theoretical predictions of (0.51-0.92)%., 2020年07月06日, 102, 1, 研究論文（学術雑誌）

Zhukova, We report new measurements of the production cross sections of pairs of charged pions and kaons as a function of their fractional energies using various fractional-energy definitions. Two different fractional-energy definitions were used and compared to the conventional fractional-energy definition reported previously. The new variables aim at either identifying dihadron cross sections in terms of single-hadron fragmentation functions, or to provide a means of characterizing the transverse momentum created in the fragmentation process. The results were obtained applying the updated initial-state radiation correction used in other recent Belle publications on light-hadron production cross sections. In addition, production cross sections of single charged pions, kaons, and protons were also updated using this initial-state radiation correction. The cross sections are obtained from a 558 fb(-1) data sample collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider., 2020年05月13日, 101, 9, 研究論文（学術雑誌）

Zhang; Z. P. Zhang; V. Zhilich; V. Zhukova; V. Zhulanov, The first dedicated search for the ηc2(1D) is carried out using the decays B+→ ηc2(1D)K+, B0 → ηc2(1D)KS0, B0→ ηc2(1D)π−K+, and B+→ ηc2(1D)π+KS0 with ηc2(1D) → hcγ. No significant signal is found. For the ηc2(1D) mass range between 3795 and 3845 MeV/c2, the branching-fraction upper limits are determined to be ℬ(B+→ ηc2(1D)K+) × ℬ(ηc2(1D) → hcγ) < 3.7 × 10−5, ℬ(B0→ ηc2(1D)K0) × ℬ(ηc2(1D) → hcγ) < 3.5 × 10−5, ℬ(B0→ ηc2(1D)π−K+) × ℬ(ηc2(1D) → hcγ) < 1.0 × 10−4, and ℬ(B+→ ηc2(1D)π+KS0) × ℬ(ηc2(1D) → hcγ) < 1.1 × 10−4 at 90% C.L. The analysis is based on the 711 fb−1 data sample collected on the ϒ(4S) resonance by the Belle detector, which operated at the KEKB asymmetric-energy e+e− collider.

Zhukova, Theories beyond the standard model often predict the existence of an additional neutral boson, the Z′.Using data collected by the Belle II experiment during 2018 at the SuperKEKB collider, we perform the first searches for the invisible decay of a Z′ in the process e⁺e⁻ → μ⁺μ⁻Z′ and of a lepton-flavor-violating Z′ in e⁺e⁻ →e±μ∓Z′. We do not find any excess of events and set 90% credibility level upper limits on the cross sections of these processes. We translate the former, in the framework of an Lμ − Lτ theory, into upper limits on the Z′ coupling constant at the level of 5 × 10⁻² − 1 for Mz′ ≤ 6 GeV/c²., 2020年04月06日, 124, 14, 141801, 141801, 研究論文（学術雑誌）

Y Zhang; Y Zhang; X Zhou; V Zhukova; V Zhulanov; A Zupanc, The Belle II detector will provide a major step forward in precision heavy flavor physics, quarkonium and exotic states, searches for dark sectors, and many other areas. The sensitivity to a large number of key observables can be improved by about an order of magnitude compared to the current measurements, and up to two orders in very clean search measurements. This increase in statistical precision arises not only due to the increased luminosity, but also from improved detector efficiency and precision for many channels. Many of the most interesting observables tend to have very small theoretical uncertainties that will therefore not limit the physics reach. This book has presented many new ideas for measurements, both to elucidate the nature of current anomalies seen in flavor, and to search for new phenomena in a plethora of observables that will become accessible with the Belle II dataset. The simulation used for the studiesinthis book was state ofthe artat the time, though weare learning a lot more about the experiment during the commissioning period. The detector is in operation, and working spectacularly well., 2019年12月01日, 2019, 12, 研究論文（学術雑誌）

A search for the decays B+→hcK+ and B0→hcKS0 is performed. Evidence for the decay B+→hcK+ is found; its significance is 4.8σ. No evidence is found for B0→hcKS0. The branching fraction for B+→hcK+ is measured to be (3.7-0.9+1.0 -0.8+0.8)×10-5; the upper limit for the B0→hcKS0 branching fraction is 1.4×10-5 at 90% C.L. In addition, a study of the ppπ+π- invariant mass distribution in the channel B+→(ppπ+π-)K+ results in the first observation of the decay ηc(2S)→ppπ+π- with 12.1σ significance. The analysis is based on the 711 fb-1 data sample collected by the Belle detector at the asymmetric-energy e+e- collider KEKB at the (4S) resonance., 2019年07月10日, 100, 1, 研究論文（学術雑誌）

T; Merola M; Miyabayashi K; Miyashita T. S; Miyata H; Mizuk R, We report measurements of sin 2 beta and cos 2 beta using a time-dependent Dalitz plot analysis of B-0 -> D((*))h(0) with D -> K-S(0)pi(+)pi(-) decays, where the light unflavored and neutral hadron h(0) is a pi(0),eta, or omega meson. The analysis uses a combination of the final data sets of the BABAR and Belle experiments containing 471 x 10(6) and 772 x 10(6) B (B) over bar pairs collected at the gamma(4S) resonance at the asymmetric-energy B factories PEP-II at SLAC and KEKB at KEK, respectively. We measure sin 2 beta = 0.80 +/- 0.14(stat) +/- 0.06(syst) +/- 0.03(model) and cos 2 beta = 0.91 +/- 0.22(stat) +/- 0.09(syst) +/- 0.07(model). The result for the direct measurement of the angle is beta = (22.5 +/- 4.4(stat) +/- 1.2(syst) +/- 0.6(model))degrees. The last quoted uncertainties are due to the composition of the D-0 -> K-S(0)pi(+)pi(-) decay amplitude model, which is newly established by a Dalitz plot amplitude analysis of a high-statistics e(+) e(-) -> c (c) over bar data sample as part of this analysis. We find the first evidence for cos 2 beta > 0 at the level of 3.7 standard deviations. The measurement excludes the trigonometric multifold solution pi/2 - beta = (68.1 +/- 0.7)degrees at the level of 7.3 standard deviations and therefore resolves an ambiguity in the determination of the apex of the CKM Unitarity Triangle. The hypothesis of beta = 0 degrees is ruled out at the level of 5.1 standard deviations, and thus CP violation is observed in B-0 -> D-(*) h(0) decays. The measurement assumes no direct CP violation in B-0 -> D-(*) h(0) decays., 2018年12月26日, 98, 11, 研究論文（学術雑誌）

We present the result of the search for the rare B meson decay of B+→+νγ with =e,μ. For the search the full data set recorded by the Belle experiment of 711 fb-1 integrated luminosity near the (4S) resonance is used. Signal candidates are reconstructed for photon energies Eγ larger than 1 GeV using a novel multivariate tagging algorithm. The novel algorithm fully reconstructs the second B meson produced in the collision using hadronic modes and was specifically trained to recognize the signal signature in combination with hadronic tag-side B meson decays. This approach greatly enhances the performance. Background processes that can mimic this signature, mainly charmless semileptonic decays and continuum processes, are suppressed using multivariate methods. The number of signal candidates is determined by analyzing the missing mass squared distribution as inferred from the signal side particles and the kinematic properties of the tag-side B meson. No significant excess over the background-only hypothesis is observed and upper limits on the partial branching fraction ΔB with Eγ>1 GeV individually for electron and muon final states as well as for the average branching fraction of both lepton final states are reported. We find a Bayesian upper limit of ΔB(B+→+νγ)<3.0×10-6 at 90% CL and also report an upper limit on the first inverse moment of the light-cone distribution amplitude of the B meson of λB>0.24 GeV at 90% CL., 2018年12月01日, 98, 11, 研究論文（学術雑誌）

We measure the inclusive production cross sections of hyperons and charmed baryons from e+e- annihilation using a 800 fb-1 data sample taken near the (4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. The feed-down contributions from heavy particles are subtracted using our data, and the direct production cross sections are presented for the first time. The production cross sections divided by the number of spin states for S=-1 hyperons follow an exponential function with a single slope parameter except for the Σ(1385)+ resonance. Suppression for Σ(1385)+ and Ξ(1530)0 hyperons is observed. Among the production cross sections of charmed baryons, a factor of 3 difference for Λc+ states over Σc states is observed. This observation suggests a diquark structure for these baryons., 2018年04月, 97, 7, 072005, 研究論文（学術雑誌）
