Abstract: Physical review / D 107(9), L091102 (2023). doi:10.1103/PhysRevD.107.L091102, We measure the $B^0$ lifetime and flavor-oscillation frequency using $B^0\to D^{(*)-}\pi^+$ decays collected by the Belle II experiment in asymmetric-energy $e^+e^-$ collisions produced by the SuperKEKB collider operating at the $\Upsilon(4S)$ resonance. We fit the decay-time distribution of signal decays, where the initial flavor is determined by identifying the flavor of the other $B$ meson in the event. The results, based on $33000$ signal decays reconstructed in a data sample corresponding to ${190}\text{fb}^{-1}$, are $\tau_{B^0} = {1.499}\pm{0.013}\pm{0.008}\;\text{ps}$, $\Delta m_d = {0.516}\pm{0.008}\pm{0.005}\;\text{ps}^{-1}$, where the first uncertainties are statistical and the second are systematic. These results are consistent with the world-average values., Published by Inst., Woodbury, NY

Abstract: Physical review / D 107(11), 112010 (2023). doi:10.1103/PhysRevD.107.112010, We propose a new algorithm for the identification of the production flavor of neutral $D$ mesons in the Belle II experiment. The algorithm exploits the correlation between the flavor of a reconstructed neutral $D$ meson (signal $D$ meson) and the electric charges of particles reconstructed in the rest of the $e^+e^-\to c \bar{c}$ event. These include those originating from the decay of the other charm hadron produced in the event, as well as those possibly produced in association with the signal $D$ meson. We develop the algorithm using simulation and calibrate it in data using decay modes that identify the flavor of the decaying neutral $D$ meson. We use a data sample of $e^+e^-$ collisions, corresponding to $362\,\mathrm{fb}^{-1}$ of integrated luminosity, collected by Belle II at center-of-mass energies near the $\Upsilon(4S)$ mass. The effective tagging efficiency in data is $(47.91 \pm 0.07 \mathrm{(stat)} \pm 0.51 \mathrm{(syst)})\%$, independent of the neutral-$D$-meson decay mode. This charm flavor tagger will approximately double the effective sample size of many $CP$-violation and charm-mixing measurements that so far have exclusively relied on neutral $D$ mesons originating from $D^{*\pm}$ decays. While developed for Belle II, the basic principles underlying the charm flavor tagger can be used in other experiments, including those at hadron colliders., Published by Inst., Woodbury, NY

Abstract: Physical review letters 130(23), 231801 (2023). doi:10.1103/PhysRevLett.130.231801, The $L_{\mu}-L_{\tau}$ extension of the standard model predicts the existence of a lepton-flavor-universality-violating $Z^{\prime}$ boson that couples only to the heavier lepton families. We search for such a $Z^\prime$ through its invisible decay in the process $e^+ e^- \to \mu^+ \mu^- Z^{\prime}$. We use a sample of electron-positron collisions at a center-of-mass energy of 10.58GeV collected by the Belle II experiment in 2019-2020, corresponding to an integrated luminosity of 79.7fb$^{-1}$. We find no excess over the expected standard-model background. We set 90$\%$-confidence-level upper limits on the cross section for this process as well as on the coupling of the model, which ranges from $3 \times 10^{-3}$ at low $Z^{\prime}$ masses to 1 at $Z^{\prime}$ masses of 8$GeV/c^{2}$., Published by APS, College Park, Md.

Abstract: We search for a light Higgs boson (A$^{0}$) decaying into a τ$^{+}$τ$^{-}$ or μ$^{+}$μ$^{-}$ pair in the radiative decays of Υ(1S). The production of Υ(1S) mesons is tagged by Υ(2S)→π$^{+}$π$^{-}$Υ(1S) transitions, using 158×10$^{6}$ Υ(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 τ$^{+}$τ$^{-}$ or μ$^{+}$μ$^{-}$ 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 Υ(1S)→γA$^{0}$ and A$^{0}$→τ$^{+}$τ$^{-}$ varying from 3.8×10$^{-6}$ to 1.5×10$^{-4}$. Our results represent an approximately twofold improvement on the current world best upper limits for the Υ(1S)→γA$^{0}$(→τ$^{+}$τ$^{-}$) production. For A$^{0}$→μ$^{+}$μ$^{-}$, the upper limits on the product branching fractions for Υ(1S)→γA$^{0}$ and A$^{0}$→μ$^{+}$μ$^{-}$ are at the same level as the world average limits, and vary from 3.1×10$^{-7}$ to 1.6×10$^{-5}$. The upper limits at 90% credibility level on the Yukawa coupling fΥ(1S) and mixing angle sin θ$_{A0}$ are also given.

Abstract: The European physical journal / C 82(4), 283 (2022). doi:10.1140/epjc/s10052-022-10180-9, We report on new flavor tagging algorithms developed to determine the quark-flavor content of bottom ( [inline-graphic not available: see fulltext]) 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 [inline-graphic not available: see fulltext] decays with flavor-specific final states reconstructed in a data set corresponding to an integrated luminosity of 62.8 fb$^{-1}$, collected at the 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., Published by Springer, Heidelberg

Abstract: Physical review letters 128(14), 142005 (2022). doi:10.1103/PhysRevLett.128.142005, The measurement of two-particle angular correlation functions in high-multiplicity $e^+ e^-$ collisions at $\sqrt{s}$ = 10.52 GeV is reported. In this study, the 89.5 fb$^{-1}$ of hadronic $e^+ e^-$ annihilation data collected by the Belle detector at KEKB are used. Two-particle angular correlation functions are measured in the full relative azimuthal angle $(Δϕ)$ and three units of pseudorapidity $(Δη)$, defined by either the electron beam axis or the event-shape thrust axis, and are studied as a function of charged-particle multiplicity. The measurement in the thrust axis analysis, with mostly outgoing quark pairs determining the reference axis, is sensitive to the region of additional soft gluon emissions. No significant anisotropic collective behavior is observed with either coordinate analyses. Near-side jet correlations appear to be absent in the thrust axis analysis. The measurements are compared to predictions from various event generators and are expected to provide new constraints to the phenomenological models in the low-energy regime., Published by APS, College Park, Md.

Abstract: Physical review / D 107(7), 072002 (2023). doi:10.1103/PhysRevD.107.072002, We present measurements of the first to fourth moments of the lepton mass squared $q^2$ of \mbox{$B \to X_c \, \ell\, \bar \nu_{\ell}$} decays for $\ell = e, \mu$ and with $X_c$ a hadronic system containing a charm quark. These results use a sample of electron-positron collisions at the $\Upsilon(4S)$ resonance corresponding to $62.8 \, \mathrm{fb}^{-1}$ of integrated luminosity and collected by the Belle II experiment in 2019 and 2020. To identify the $X_c$ system and reconstruct $q^2$, one of the $B$ mesons from an $\Upsilon(4S) \to B \kern 0.18em\overline{\kern -0.18em B}$ decay is fully reconstructed in a hadronic decay mode using a multivariate $B$ tagging algorithm. We report raw and central moments for $ q^2 > 1.5 \; \mathrm{GeV^2/c^4}$ up to $q^2 > 8.5 \; \mathrm{GeV^2/c^4}$, probing up to 77% of the accessible \mbox{$B \to X_c \, \ell\, \bar \nu_{\ell}$} phase space. This is the first measurement of moments in the experimentally challenging range of $[ 1.5, 2.5 ] \, \mathrm{GeV^2/c^4}$., Published by Inst., Woodbury, NY

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 report results from the first search for the rare penguin-dominated decay mode B0→K0SK0Sγ, which can result from the production of tensor mesons f(1270) and f′(1525) in association with a photon. The search uses the full data sample of 772×106 B¯B pairs collected with the Belle detector at the KEKB asymmetric-energy e+e− collider. No statistically significant signals are observed in the K0SK0S invariant mass range 1 GeV/c2

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: Physical review / D 106(1), 012006 (2022). doi:10.1103/PhysRevD.106.012006, We report results from the first search for the rare penguin-dominated decay mode $B^0 → K_S^0 K_S^0 γ$, which can result from the production of tensor mesons $f(1270)$ and $f′(1525)$ in association with a photon. The search uses the full data sample of $772 × 10^6 B\bar{B}$ pairs collected with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. No statistically significant signals are observed in the $K_S^0 K_S^0$ invariant mass range $1 GeV/c^2 < M_{K^0_S K_S^0} < 3$ $GeV/c^2$, and the following upper limits at the 90% confidence level are obtained: $\mathcal{B}(B^0 → K_S^0 K_S^0 γ) < 5.8 × 10^{-7}$, $\mathcal{B}(B^0 → f_2 γ)$ $× \mathcal{B}(f_2 (1270) → K_S^0 K_S^0) < 3.1 × 10^{-7}$, and $\mathcal{B}(B^0 → f_{2}′γ) ×\mathcal{B} (f_{2}′(1525) → K_S^0 K_S^0) < 2.1 × 10^{-7}$. In addition, 90% confidence-level upper limits in the range of $[0.7–2.9] × 10^{-7}$ are also obtained on the $B^0 → K_S^0 K_S^0 γ$ branching fraction in bins of $M_{K_S^0 K_S^0}$., Published by Inst., Melville, NY

Abstract: We present a search for the decays of B0 mesons into a final state containing a Λ baryon and missing energy. These results are obtained from a 711 fb−1 data sample that contains 772×106 B¯B pairs and was collected near the Υ(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 Λ. No evidence for these decays is found, and we set 90% confidence level upper limits on the branching fractions in the range 2.1–3.8×10−5. This measurement provides the world’s most restrictive limits, with implications for baryogenesis and dark matter production.

Abstract: A search for double-heavy tetraquark state candidates Xcc¯s¯s decaying to D+sD+s and D*+sD*+s is presented for the first time using the data samples of 102×106 Υ(1S) and 158×106 Υ(2S) events, and the data samples at √s=10.52, 10.58, and 10.867 GeV corresponding to integrated luminosities of 89.5, 711.0, and 121.4 fb−1, respectively, accumulated with the Belle detector at the KEKB asymmetric energy electron-positron collider. The invariant-mass spectra of the D+sD+s and D*+sD*+s are studied to search for possible resonances. No significant signals are observed, and the 90% confidence level upper limits on the product branching fractions [B(Υ(1S,2S)→Xcc¯s¯s+anything)×B(Xcc¯s¯s→D+sD+s(D*+sD*+s))] in Υ(1S,2S) inclusive decays and the product values of Born cross section and branching fraction [σ(e+e−→Xcc¯s¯s+anything)×B(Xcc¯s¯s→D+sD+s(D*+sD*+s))] in e+e− collisions at √s=10.52, 10.58, and 10.867 GeV under different assumptions of Xcc¯s¯s masses and widths are obtained.

Abstract: We present a measurement of the branching fractions of the Cabibbo favored ̄B0 → Dþπ− and theCabibbo suppressed ̄B0 → DþK− decays. We find Bð ̄B0 → Dþπ−Þ ¼ ð2.48 0.01 0.09 0.04Þ ×10−3 and Bð ̄B0 → DþK−Þ ¼ ð2.03 0.05 0.07 0.03Þ × 10−4 decays, where the first uncertainty isstatistical, the second is systematic, and the third uncertainty is due to the Dþ → K−πþπþ branchingfraction. The ratio of branching fractions of ̄B0 → DþK− and ̄B0 → Dþπ− is measured to beR D ¼ ½8.19 0.20ðstatÞ 0.23ðsystÞ × 10−2. These measurements are performed using the full Belledataset, which corresponds to 772 × 10 6B ̄B pairs and use the Belle II software framework for data analysis.

Abstract: Physical review / D 105(9), L091101 (2022). doi:10.1103/PhysRevD.105.L091101, We present the first observation of the Ωc0→Ω-μ+νμ decay and present measurements of the branching fraction ratios of the Ωc0→Ω-ℓ+νℓ decays compared to the reference mode Ωc0→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 Ωc0 signal yields are extracted by fitting MΩℓ and MΩπ spectra. The branching fraction ratios B(Ωc0→Ω-e+νe)/B(Ωc0→Ω-π+) and B(Ωc0→Ω-μ+νμ)/B(Ωc0→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(Ωc0→Ω-e+νe)/B(Ωc0→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., Published by Inst., Woodbury, NY

Abstract: Physical review letters 128(8), 081804 (2022). doi:10.1103/PhysRevLett.128.081804, 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 $\Upsilon(2S)\to \pi^+ \pi^- \Upsilon(1S)$ transitions, using 158 million $\Upsilon(2S)$ 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 $\Upsilon(1S)\to \gamma A^0$ and $A^0\to \tau^+\tau^-$ varying from $3.8\times10^{-6}$ to $1.5\times10^{-4}$. Our results represent an approximately twofold improvement on the current world best upper limits for the $\Upsilon(1S)\to \gamma A^0(\to \tau^+\tau^-)$ production. For $A^0\to \mu^+\mu^-$, the upper limits on the product branching fractions for $\Upsilon(1S)\to \gamma A^0$ and $A^0\to \mu^+\mu^-$ are at the same level as the world average limits, and vary from $3.1\times10^{-7}$ to $1.6\times10^{-5}$. The upper limits at 90% C.L. on the Yukawa coupling $f_{\Upsilon(1S)}$ and mixing angle ${\rm sin}\theta_{A^0}$ are also given., Published by APS, College Park, Md.

Abstract: Physical review / D 105(1), L011102 (2022). doi:10.1103/PhysRevD.105.L011102, 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 $\Xi_c^0 \to \Lambda K_S^0$, $\Xi_c^0 \to \Sigma^0 K_S^0$, and $\Xi_c^0 \to \Sigma^+ K^-$. Taking the decay $\Xi_c^0 \to \Xi^- \pi^+$ as the normalization mode, we measure the branching fraction ratio ${\cal B}(\Xi_c^0 \to \Lambda K_S^0)/{\cal B}(\Xi_c^0 \to \Xi^- \pi^+) = 0.229\pm0.008\pm0.012$ with improved precision, and measure the branching fraction ratios ${\cal B}(\Xi_c^0 \to \Sigma^0 K_S^0)/{\cal B}(\Xi_c^0 \to \Xi^- \pi^+) = 0.038\pm0.006\pm0.004$ and ${\cal B}(\Xi_c^0 \to \Sigma^+ K^-)/{\cal B}(\Xi_c^0 \to \Xi^- \pi^+) = 0.123\pm0.007\pm0.010$ for the first time. Taking into account the previously measured branching fraction ${\cal B}(\Xi_c^0 \to \Xi^- \pi^+) = (1.80\pm0.52)\%$, the absolute branching fractions are determined to be ${\cal B}(\Xi_c^0 \to \Lambda K_S^0) = (4.12\pm 0.14\pm0.21\pm1.19) \times 10^{-3}$, ${\cal B}(\Xi_c^0 \to \Sigma^0 K_S^0) = (0.69\pm 0.10\pm 0.08\pm 0.20) \times 10^{-3}$, and ${\cal B}(\Xi_c^0 \to \Sigma^+ K^-) = (2.21\pm 0.13\pm0.19\pm 0.64) \times 10^{-3}$. The first and second uncertainties above are statistical and systematic, respectively, while the third ones arise from the uncertainty of the branching fraction of $\Xi_c^0 \to \Xi^- \pi^+$., Published by Inst., Woodbury, NY

Abstract: Physical review letters 130(9), 091902 (2022). doi:10.1103/PhysRevLett.130.091902, We study the processes $e^+e^-\to\omega\chi_{bJ}(1P)$ ($J$ = 0, 1, or 2) using samples at center-of-mass energies $\sqrt{s}$ = 10.701, 10.745, and 10.805 GeV, corresponding to 1.6, 9.8, and 4.7 fb$^{-1}$ of integrated luminosity, respectively. These data were collected with the Belle II detector during special operations of the SuperKEKB collider above the $\Upsilon(4S)$ resonance. We report the first observation of $\omega\chi_{bJ}(1P)$ signals at $\sqrt{s}$ = 10.745 GeV. By combining Belle II data with Belle results at $\sqrt{s}$ = 10.867 GeV, we find energy dependencies of the Born cross sections for $e^+e^-\to \omega\chi_{b1,b2}(1P)$ to be consistent with the shape of the $\Upsilon(10753)$ state. These data indicate that the internal structures of the $\Upsilon(10753)$ and $\Upsilon(10860)$ states may differ. Including data at $\sqrt{s}$ = 10.653 GeV, we also search for the bottomonium equivalent of the $X(3872)$ state decaying into $\omega\Upsilon(1S)$. No significant signal is observed for masses between 10.45 and 10.65 GeV/$c^2$., Published by APS, College Park, Md.

Abstract: Physical review / D 105(5), L051101 (2022). doi:10.1103/PhysRevD.105.L051101, We present a search for the decays of B0 mesons into a final state containing a Λ baryon and missing energy. These results are obtained from a 711 fb−1 data sample that contains 772×106 B¯B pairs and was collected near the Υ(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 Λ. No evidence for these decays is found, and we set 90% confidence level upper limits on the branching fractions in the range 2.1–3.8×10−5. This measurement provides the world’s most restrictive limits, with implications for baryogenesis and dark matter production., Published by APS, Melville, NY

Abstract: Using the entire data sample of 980 fb−1 collected with the Belle detector at the KEKB asymmetric-energyeþe− collider, we present measurements of the branching fractions of the Cabibbo-favored decays Ξ0c → ΛK0S,Ξ0c → Σ0K0S, and Ξ0c → ΣþK−. Taking the decay Ξ0c → Ξ−πþ as the normalization mode, we measure thebranching fraction ratio BðΞ0c → ΛK0SÞ=BðΞ0c → Ξ−πþ Þ ¼ 0.229 0.008 0.012 with improved precision,and measure the branching fraction ratios BðΞ0c → Σ0K0SÞ=BðΞ0c → Ξ−πþ Þ ¼ 0.038 0.006 0.004and BðΞ0c → ΣþK−Þ=BðΞ0c → Ξ−πþ Þ ¼ 0.123 0.007 0.010 for the first time. Taking intoaccount the branching fraction of the normalization mode, the absolute branching fractions are determinedto be BðΞ0c → ΛK0SÞ ¼ ð3.27 0.11 0.17 0.73Þ × 10−3, BðΞ0c → Σ0K0SÞ ¼ ð0.54 0.09 0.060.12Þ × 10−3, and BðΞ0c → ΣþK−Þ ¼ ð1.76 0.10 0.14 0.39Þ × 10−3. The first and second uncer-tainties above are statistical and systematic, respectively, while the third ones arise from the uncertainty of thebranching fraction of Ξ0c → Ξ−πþ

Abstract: Physical review / D 104(7), 072008 (2021). doi:10.1103/PhysRevD.104.072008, Using 980.6 $\rm fb^{-1}$ of data collected with the Belle detector operating at the KEKB asymmetric-energy $e^+e^-$ collider, we present a measurement of the branching fraction of the singly Cabibbo-suppressed decay $\Lambda_c^+ \to p \omega$. A clear $\Lambda_c^+$ signal is observed for $\Lambda_c^+ \to p \omega$ with a statistical significance of 9.1 standard deviations, and we measure the ratio of branching fractions ${\cal B}(\Lambda_c^+ \to p \omega)/{\cal B}(\Lambda_c^+ \to p K^- \pi^+) = (1.32 \pm 0.12 (\rm stat) \pm 0.10 (\rm syst))\times 10^{-2}$, from which we infer the branching fraction ${\cal B}(\Lambda_c^+ \to p \omega) = (8.27 \pm 0.75 (\rm stat) \pm 0.62 (\rm syst) \pm 0.42 (\rm ref))\times 10^{-4}$. The first quoted uncertainty is statistical, the second systematic, and the third from the reference mode $\Lambda_c^+ \to p K^- \pi^+$., Published by APS, Melville, NY

Abstract: doi:10.1103/PhysRevD.104.112011, We present the measurement of the first to fourth order moments of the four-momentum transfer squared, $q^2$, of inclusive $B \rightarrow X_c \ell^+ \nu_{\ell}$ decays using the full Belle data set of 711 $\mathrm{fb}^{-1}$ of integrated luminosity at the $\Upsilon(4S)$ resonance where $\ell = e, \mu$. The determination of these moments and their systematic uncertainties open new pathways to determine the absolute value of the CKM 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 $\mathrm{GeV}^2$ in steps of 0.5 $\mathrm{GeV}^2$ up to a value of 10.0 $\mathrm{GeV}^2$. 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.

Abstract: Physical review / D 105(1), 012003 (2022). doi:10.1103/PhysRevD.105.012003, We present a measurement of the branching fractions of the Cabibbo favored $\overline{B}{}^0\rightarrow D^{+}\pi^{-}$ and the Cabibbo suppressed $\overline{B}{}^0\rightarrow D^{+}K^{-}$ decays. We find $\mathcal{B}(\overline{B}{}^0\rightarrow D^{+}\pi^{-}) = (2.48 \pm 0.01 \pm 0.09 \pm 0.04) \times 10^{-3}$ and $\mathcal{B}(\overline{B}{}^0\rightarrow D^{+}K^{-})= (2.03 \pm 0.05 \pm 0.07 \pm 0.03) \times 10^{-4}$ decays, where the first uncertainty is statistical, the second is systematic, and the third uncertainty is due to the $D^{+} \rightarrow K^{-}\pi^{+}\pi^{+}$ branching fraction. The ratio of branching fractions of $\overline{B}{}^0\rightarrow D^{+}K^{-}$ and $\overline{B}{}^0\rightarrow D^{+}\pi^{-}$ is measured to be $R^{D} = [8.19 \pm 0.20(\rm stat) \pm 0.23(\rm syst)] \times 10^{-2} $. These measurements are performed using the full Belle data set, which corresponds to $772 \times 10^{6} B\overline{B} $ pairs., Published by Inst., Melville, NY

Abstract: Physical review / D 105(5), L051101 (2022). doi:10.1103/PhysRevD.105.L051101, We present a search for the decays of $B^0$ mesons into a final state containing a $Λ$ baryon and missing energy. These results are obtained from a 711 fb$^{-1}$ data sample that contains $772 × 10^6$ $B\bar{B}$ pairs and was collected near the $ϒ(4S)$ 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 $Λ$. No evidence for these decays is found, and we set 90% confidence level upper limits on the branching fractions in the range $2.1–3.8 × 10^{-5}$. This measurement provides the world’s most restrictive limits, with implications for baryogenesis and dark matter production., Published by Inst., Melville, NY

Abstract: We present the measurement of the first to fourth order moments of the four-momentum transfer squared, q$^{2}$, of inclusive B ��x$_{c}$��$^{+}$��$_{��}$ decays using the full Belle dataset of 711 fb$^{-1}$ of integrated luminosity at the ��(4S) resonance where ��=e, ��. 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 GeV$^{2}$ in steps of 0.5 GeV$^{2}$ up to a value of 10.0 GeV$^{2}$. 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.

Abstract: Physical review letters 130(18), 181803 (2023). doi:10.1103/PhysRevLett.130.181803, We search for lepton-flavor violating $\tau^-\to e^-\alpha$ and $\tau^-\to\mu^-\alpha$ decays, where $\alpha$ is an invisible spin-0 boson. The search uses electron-positron collisions at $10.58$ GeV center-of-mass energy with an integrated luminosity of $62.8$ fb$^{-1}$, produced by the SuperKEB collider and collected with the Belle II detector. We search for an excess in the lepton-energy spectrum of the known $\tau^-\to e^-\bar\nu_e \nu_\tau$ and $\tau^-\to \mu^-\bar\nu_\mu \nu_\tau$ decays. We report 95%-confidence-level upper limits on the branching-fraction ratio ${\mathcal B}(\tau^-\to e^- \alpha) / {\mathcal B}(\tau^- \to e^- \bar\nu_e \nu_\tau)$ in the range $(1.1-9.7) \times 10^{-3}$ and on ${\mathcal B}(\tau^-\to \mu^- \alpha) / {\mathcal B}(\tau^- \to \mu^- \bar\nu_\mu \nu_\tau)$ in the range $(0.7-12.2) \times 10^{-3}$ for $\alpha$ masses between $0$ GeV/c$^2$ and 1.6 GeV/c$^2$. These results provide the most stringent bounds on invisible boson production from $\tau$ decays., Published by APS, College Park, Md.

Abstract: Physical review letters 130(7), 071804 (2023). doi:10.1103/PhysRevLett.130.071804, The dark photon $A^\prime$ and the dark Higgs boson $h^\prime$ are hypothetical particles predicted in many dark sector models. We search for the simultaneous production of $A^\prime$ and $h^\prime$ in the dark Higgsstrahlung process $e^{+}e^{-}\rightarrow A^\prime \, h^\prime$ with $A^\prime \rightarrow \mu^+\mu^-$ and $ h^\prime$ invisible in electron-positron collisions at a center-of-mass energy of 10.58 GeV collected by the Belle II experiment in 2019. With an integrated luminosity of 8.34 fb$^{-1}$ we observe no evidence for signal. We obtain exclusion limits at 90% Bayesian credibility in the range 1.7--5.0 fb on the cross section and in the range $1.7 \times10^{-8}$--$200 \times10^{-8}$ on the effective coupling $\varepsilon^2 \times \alpha_D$, for $A^\prime$ mass 4.0 GeV/$c^2$ $< M_{A^\prime}< 9.7$ GeV/$c^2$ and $h^\prime$ mass $M_{h^\prime} < M_{A^\prime}$, where $\varepsilon$ is the mixing strength between the Standard Model and the dark photon and $\alpha_D$ is the coupling of the dark photon to the dark Higgs boson. Our limits are the first in this mass range., Published by APS, College Park, Md.

Abstract: Physical review / D 107(11), 112009 (2023). doi:10.1103/PhysRevD.107.112009, We report measurements of the branching fraction and $CP$ asymmetry in $B^{0} \to \pi^{0} \pi^{0}$ decays reconstructed at Belle II in an electron-positron collision sample containing $198 \times 10^{6}$$B\overline{B}$ pairs. We measure a branching fraction $\mathcal{B}(B^0 \rightarrow \pi^0 \pi^0) = (1.38 \pm 0.27 \pm 0.22) \times 10^{-6}$ and a $\it CP$ asymmetry $\mathcal{A}_{\rm CP}(B^0 \rightarrow \pi^0 \pi^0) = 0.14 \pm 0.46 \pm 0.07$, where the first uncertainty is statistical and the second is systematic., Published by Inst., Woodbury, NY
