Abstract: We present a measurement of the branching fractions of the Cabibbo favored $\overline{B}$$^{0}$ →D$^{+}$π$^{–}$ and the Cabibbo suppressed $\overline{B}$$^{0}$ →D$^{+}$K$^{–}$ decays. We find B($\overline{B}$$^{0}$ →D$^{+}$π$^{–}$)=(2.48±0.01±0.09±0.04)×10$^{–3}$ and B($\overline{B}$$^{0}$ →D$^{+}$K$^{–}$)=(2.03±0.05±0.07±0.03)×10$^{–4}$ decays, where the first uncertainty is statistical, the second is systematic, and the third uncertainty is due to the D$^{+}$→K$^{–}$ π$^{+}$π$^{–}$ branching fraction. The ratio of branching fractions of $\overline{B}$$^{0}$ →D$^{+}$K$^{–}$ and $\overline{B}$$^{0}$ →D$^{+}$π$^{–}$ is measured to be R$^{D}$=[8.19±0.20(stat)±0.23(syst)]×10$^{–2}$. These measurements are performed using the full Belle dataset, which corresponds to 772×10$^{6}$ B$\overline{B}$ pairs and use the Belle II software framework for data analysis.

Abstract: We present the first observation of the Ω0c→Ω−μ+νμ decay and present measurements of the branching fraction ratios of the Ω0c→Ω−ℓ+νℓ decays compared to the reference mode Ω0c→Ω−π+, (ℓ=e or μ). This analysis is based on 89.5 fb−1, 711 fb−1, and 121.1 fb−1 data samples collected with the Belle detector at the KEKB asymmetric-energy e+e− collider at the center-of-mass energies of 10.52 GeV, 10.58 GeV, and 10.86 GeV, respectively. The Ω0c signal yields are extracted by fitting MΩℓ and MΩπ spectra. The branching fraction ratios B(Ω0c→Ω−e+νe)/B(Ω0c→Ω−π+) and B(Ω0c→Ω−μ+νμ)/B(Ω0c→Ω−π+) are measured to be 1.98±0.13(stat)±0.08(syst) and 1.94±0.18(stat)±0.10(syst), respectively. The ratio of B(Ω0c→Ω−e+νe)/B(Ω0c→Ω−μ+νμ) is measured to be 1.02±0.10(stat)±0.02(syst), which is consistent with the expectation of lepton flavor universality.

Abstract: We measure the branching fractions and CP asymmetries for the decays B0→¯D0π0 and B+→¯D0π+, using a data sample of 772×106 B¯B pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB e+e− collider. The branching fractions obtained and direct CP asymmetries are B(B0→¯D0π0)=[2.70±0.06(stat)±0.10(syst)]×10−4, B(B+→¯D0π+)=[4.53±0.02(stat)±0.15(syst)]×10−3, ACP(B0→¯D0π0)=[+0.42±2.05(stat)±1.22(syst)]%, and ACP(B+→¯D0π+)=[+0.19±0.36(stat)±0.57(syst)]%. The measurements of B are the most precise to date and are in good agreement with previous results, as is the measurement of ACP(B+→¯D0π+). The measurement of ACP for B0→¯D0π0 is the first for this mode, and the value is consistent with Standard Model expectations.

Abstract: [EN] We report results from a search for the decay B-s(0) -> eta eta using 121.4 fb(-1) of data collected at the Upsilon(5S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We do not observe any signal and set an upper limit on the branching fraction of 14.3 x 10(-5) at 90% confidence level. This result represents a significant improvement over the previous most stringent limit.

Abstract: Physical review / D 103(11), L111101 (2021). doi:10.1103/PhysRevD.103.L111101, We report results from a study of the spin and parity of $\Xi_ c ( 2970 )^ +$ a 980 fb$^{��1}$ data sample collected by the Belle detector at the KEKB asymmetric-energy e��e��collider. The decay angledistributions in the chain $\Xi_ c ( 2970 )^ +$ $\to \Xi_{c}(2645)^0 \pi^+ \to \Xi_{c}^+ \pi^- \pi^+$ are analyzed to determine the spin of this charmed-strange baryon. The angular distributions strongly favor the ��c��2970��spin 1/2 over 3/2 or 5/2, under an assumption that the lowest partial wave dominates in the decay. We also measure the ratio of $\Xi_ c ( 2970 )^ +$ decay branching fractions R = $\mathcal{B}$ [\Xi_ c ( 2970 )^ + \to\Xi_{c}(2645)^0 \pi^+$]= $\mathcal{B}[$\Xi_ c ( 2970 )^ + \to \Xi_{c}^0 \pi^+$]$ = 1.670.29(stat)_{��0.09}^{+0.15}$(syst)$\pm$0.25, where the last uncertainty is due to possible isospin-symmetry-breaking effects. This R value favors the spin-parity $J^P$ 1/2$^+$ with the spin of the light-quark degrees offreedom $s_l$ = 0. This is the first determination of the spin and parity of a charmed-strange baryon, Published by American Physical Society, Melville, NY

Abstract: International audience; We present a search for the lepton-flavor-violating decays B0→τ±ℓ∓, where ℓ=(e,μ), using the full data sample of 772×106 BB¯ pairs recorded by 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. The τ± lepton is reconstructed indirectly using the momentum of the reconstructed B and that of the ℓ∓ from the signal decay. We find no evidence for B0→τ±ℓ∓ decays and set upper limits on their branching fractions at 90% confidence level of B(B0→τ±μ∓)<1.5×10-5 and B(B0→τ±e∓)<1.6×10-5.

Abstract: Using data samples of 89.5 and 711fb$^{-1}$ recorded at energies of $\sqrt{s}$=10.52 and 10.58 GeV, respectively, with the Belle detector at the KEKB e$^{+}$e$^{-}$ collider, we report measurements of branching fractions of semileptonic decays Ξ$_{c}$$^{0}$ → Ξ$^{-}$ℓ$^{+}$ν$_{ℓ}$(ℓ=e or μ) and the CP-asymmetry parameter of Ξ$_{c}$$^{0}$ → Ξ$^{-}$π$^{+}$ decay. The branching fractions are measured to be B(Ξ$_{c}$$^{0}$ → Ξ$^{-}$e$^{+}$ν$_{e}$)= 1.31±0.04±0.07±0.38)% and B(Ξ$_{c}$$^{0}$ → Ξ$^{-}$μ$^{+}$ν$_{μ}$ = (1.27±0.06±0.10±0.37)% , and the decay parameter α$_{Ξπ}$ is measured to be 0.63±0.03±0.01 with much improved precision compared with the current world average. The corresponding ratio B(Ξ$_{c}$$^{0}$ → Ξ$^{-}$e$^{+}$ν$_{e}$) /B(Ξ$_{c}$$^{0}$ → Ξ$^{-}$μ$^{+}$ν$_{μ}$) is 1.03±0.05±0.07, which is consistent with the expectation of lepton flavor universality. The first measured asymmetry parameter A$_{CP}$=(α$_{Ξ^{-}π^{+}}$+α$_{Ξ^{+}π^{-}}$)/(α$_{Ξ^{-}π^{+}}$+α$_{Ξ^{+}π^{-}}$) = 0.024±0.052±0.014 is found to be consistent with zero. The first and the second uncertainties above are statistical and systematic, respectively, while the third ones arise due to the uncertainty of the Ξ$_{c}$$^{0}$ → Ξ$^{-}$π$^{+}$ branching fraction.

Abstract: The first measurements of differential branching fractions of inclusive semileptonic B → X$_{u}$ℓ$^{+}$ν$_{ℓ}$ decays are performed using the full Belle data set of 711 fb$^{-1}$ of integrated luminosity at the Υ(4S) resonance and for ℓ=e, μ. With the availability of these measurements, new avenues for future shape-function model-independent determinations of the Cabibbo-Kobayashi Maskawa matrix element |Vx$_{ub}$| 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$_{u}$ℓ$^{+}$ν$_{ℓ}$ decays and other processes, and corrected for resolution and acceptance effects.

Abstract: For the first time we search for the η$_{c2}$(1D) in e$^{+}$e$^{-}$→γη$_{c2}$(1D) at $\sqrt{s}$=10.52, 10.58, and 10.867 GeV with data samples of 89.5 fb$^{-1}$, 711 fb$^{-1}$, and 121.4 fb$^{-1}$, respectively, accumulated with the Belle detector at the KEKB asymmetric energy electron-positron collider. No significant η$_{c2}$(1D) signal is observed in the mass range between 3.8 and 3.88 GeV/c2. The upper limit at 90% confidence level on the product of the Born cross section for e+e−→γηc2(1D) and branching fraction for η$_{c2}$(1D)→γh$_{c}$(1P) is determined to be σ(e$^{+}$e$^{-}$→γη$_{c2}$(1D))B(η$_{c2}$(1D)→γh$_{c}$(1P))

Abstract: A search for the flavor-changing neutral-current decay B$^{+}$→K$^{+}$ν$\overline{ν}$ 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+ν¯ν decay, but also the inclusive properties of the other B meson in the Υ(4S)→B$\overline{B}$ 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$^{+}$ν$\overline{ν}$ of 4.1×10$^{-5}$ is set at the 90% confidence level.

Abstract: We report the result for a search for the leptonic decay of B$^{+}$ → μ$^{+}$ν$_{μ}$ using the full Belle dataset of 711 fb$^{-1}$ of integrated luminosity at the ϒ(4S) resonance. In the Standard Model leptonic B-meson decays are helicity and Cabibbo-Kobayashi-Maskawa suppressed. To maximize sensitivity an inclusive tagging approach is used to reconstruct the second B meson produced in the collision. The directional information from this second B meson is used to boost the observed μ into the signal B-meson rest frame, in which the μ has a monochromatic momentum spectrum. Though its momentum is smeared by the experimental resolution, this technique improves the analysis sensitivity considerably. Analyzing the μ momentum spectrum in this frame we find B(B$^{+}$ → μ$^{+}$ν$_{μ}$) = 5.3 ± 2.0 ± 0.9) × 10$^{-7}$ with a one-sided significance of 2.8 standard deviations over the background-only hypothesis. This translates to a frequentist upper limit of B(B$^{+}$ → μ$^{+}$ν$_{μ}$) < 8.6 × 10$^{-7}$ at 90% confidence level. The experimental spectrum is then used to search for a massive sterile neutrino, B$^{+}$ → μ$^{+}$N, but no evidence is observed for a sterile neutrino with a mass in a range of 0–1.5 GeV. The determined B$^{+}$ → μ$^{+}$ν$_{μ}$ branching fraction limit is further used to constrain the mass and coupling space of the type II and type III two-Higgs-doublet models.

Abstract: We report the first measurement of the charm-mixing parameter y$_{CP}$ in D$^{0}$ decays to the CP-odd final state K0¦Sω. The study uses the full Belle e$^{+}$e$^{-}$ annihilation data sample of 976 fb$^{-1}$ taken at or near the Υ(4S) centre-of-mass energy. We find y$_{CP}$=(0.96±0.91±0.62(+0.17)¦(-0.00))%, where the first uncertainty is statistical, the second is systematic due to event selection and background, and the last is due to possible presence of CP-even decays in the data sample.

Abstract: 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 $558\,{\rm fb}^{-1}$ data sample collected at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^+ e^-$ collider., Comment: 12 pages, 9 figures, submitted to PRD

Abstract: This work reports the first observation of azimuthal asymmetries around the thrust axis in $e^+e^-$ annihilation of pairs of back-to-back charged pions in one hemisphere, and $\pi^0$ and $\eta$ mesons in the opposite hemisphere. These results are complemented by a new analysis of pairs of back-to-back charged pions. The $\pi^0$ and $\eta$ asymmetries rise with the relative momentum $z$ of the detected hadrons as well as with the transverse momentum with respect to the thrust axis. These asymmetries are sensitive to the Collins fragmentation function $H_1^{\perp}$ and provide complementary information to previous measurements with charged pions and kaons in the final state. In particular, the $\eta$ final states will provide additional information on the flavor structure of $H_1^{\perp}$. This is the first measurement of the explicit transverse-momentum dependence of the Collins fragmentation function from Belle data. It uses a dataset of 980.4~fb$^{-1}$ collected by the Belle experiment at or near a center-of-mass energy of 10.58 GeV., Comment: 31 pages, 14 figures, submitted to PRD

Abstract: We present the first measurements of branching fractions of rare tau-lepton decays, τ-→π-ντℓ+ℓ- (ℓ=e or μ), using a data sample corresponding to 562 fb-1 collected at a center-of-mass energy of 10.58 GeV with the Belle detector at the KEKB asymmetric-energy e+e- collider. The τ-→π-ντe+e- decay is observed for the first time with 7.0σ significance. The partial branching fraction determined by the structure-dependent mechanisms mediated by either a vector or an axial-vector current for the mass region Mπee>1.05 GeV/c2 is measured to be B(τ-→π-ντe+e-)[Mπ-e+e->1.05 GeV/c2]=(5.90±0.53±0.85±0.11)×10-6, where the first uncertainty is statistical, the second is systematic, and the third is due to model dependence. In the full phase space, due to the different detection efficiencies for the structure-dependent mechanisms mediated by axial-vector and vector currents, the branching fraction varies from BA(τ-→π-ντe+e-)=(1.46±0.13±0.21)×10-5 to BV(τ-→π-ντe+e-)=(3.01±0.27±0.43)×10-5, respectively. An upper limit is set on the branching fraction of the τ-→π-ντμ+μ- decay, B(τ-→π-ντμ+μ-)

Abstract: We present first evidence that the cosine of the CP-violating weak phase 2β is positive, and hence exclude trigonometric multifold solutions of the Cabibbo-Kobayashi-Maskawa (CKM) Unitarity Triangle using a time-dependent Dalitz plot analysis of B^{0}→D^{(*)}h^{0} with D→K_{S}^{0}π^{+}π^{-} decays, where h^{0}∈{π^{0},η,ω} denotes a light unflavored and neutral hadron. The measurement is performed combining the final data sets of the BABAR and Belle experiments collected at the ϒ(4S) resonance at the asymmetric-energy B factories PEP-II at SLAC and KEKB at KEK, respectively. The data samples contain (471±3)×10^{6}BB[over ¯] pairs recorded by the BABAR detector and (772±11)×10^{6}BB[over ¯] pairs recorded by the Belle detector. The results of the measurement are sin2β=0.80±0.14(stat)±0.06(syst)±0.03(model) and cos2β=0.91±0.22(stat)±0.09(syst)±0.07(model). The result for the direct measurement of the angle β of the CKM Unitarity Triangle is β=[22.5±4.4(stat)±1.2(syst)±0.6(model)]°. The measurement assumes no direct CP violation in B^{0}→D^{(*)}h^{0} decays. The quoted model uncertainties are due to the composition of the D^{0}→K_{S}^{0}π^{+}π^{-} decay amplitude model, which is newly established by performing a Dalitz plot amplitude analysis using a high-statistics e^{+}e^{-}→cc[over ¯] data sample. CP violation is observed in B^{0}→D^{(*)}h^{0} decays at the level of 5.1 standard deviations. The significance for cos2β>0 is 3.7 standard deviations. The trigonometric multifold solution π/2-β=(68.1±0.7)° is excluded at the level of 7.3 standard deviations. The measurement resolves an ambiguity in the determination of the apex of the CKM Unitarity Triangle.
