High Energy Physics - Experiment - Abstract
We report a search for lepton-flavor-violating decays $\tau^- \to \ell^- \phi$ ($\ell^- =e^-,\mu^-$) at the Belle II experiment, using a sample of electron-positron data produced at the SuperKEKB collider in 2019-2021 and corresponding to an integrated luminosity of 190 fb$^{-1}$. We use a new untagged selection for $e^+e^- \to \tau^+\tau^-$ events, where the signal $\tau$ is searched for as a neutrinoless final state of a single charged lepton and a $\phi$ meson and the other $\tau$ is not reconstructed in any specific decay mode, in contrast to previous measurements by the BaBar and Belle experiments. We find no evidence for $\tau^- \to \ell^- \phi$ decays and obtain upper limits on the branching fractions at 90% confidence level of 23 $\times 10^{-8}$ and 9.7$\times 10^{-8}$ for $\tau^- \rightarrow e^-\phi$ and $\tau^- \rightarrow \mu^-\phi$, respectively

- Abstract
We report measurements of the ratios of branching fractions for B→D¯(*)πℓ+νℓ and B→D¯(*)π+π−ℓ+νℓ relative to B→D¯*ℓ+νℓ decays with ℓ=e, μ. These results are obtained from a data sample that contains 772×106BB¯ pairs collected near the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric energy e+e− collider. Fully reconstructing both B mesons in the event, we obtain B(B0→D¯0π−ℓ+νℓ)B(B0→D*−ℓ+νℓ)=(7.23±0.36±0.14)%, B(B+→D−π+ℓ+νℓ)B(B+→D¯*0ℓ+νℓ)=(6.78±0.24±0.18)%, B(B0→D¯*0π−ℓ+νℓ)B(B0→D*−ℓ+νℓ)=(11.10±0.48±0.23)%, B(B+→D*−π+ℓ+νℓ)B(B+→D¯*0ℓ+νℓ)=(9.50±0.33±0.34)%, B(B0→D−π+π−ℓ+νℓ)B(B0→D*−ℓ+νℓ)=(2.91±0.37±0.26)%, B(B+→D¯0π+π−ℓ+νℓ)B(B+→D¯*0ℓ+νℓ)=(3.10±0.26±0.22)%, B(B0→D*−π+π−ℓ+νℓ)B(B0→D*−ℓ+νℓ)=(0.99±0.43±0.20)%, B(B+→D¯*0π+π−ℓ+νℓ)B(B+→D¯*0ℓ+νℓ)=(1.25±0.27±0.15)%, where the uncertainties are statistical and systematic, respectively. These are the most precise measurements of these branching fraction ratios to date. The invariant mass spectra of the Dπ, D*π, and Dππ systems are studied, and the branching fraction products B(B0→D2*−ℓ+νℓ)×B(D2*−→D¯0π−)=(0.157±0.015±0.005)%, B(B+→D¯0*0ℓ+νℓ)×B(D¯0*0→D−π+)=(0.054±0.022±0.005)%, B(B+→D¯2*0ℓ+νℓ)×B(D¯2*0→D−π+)=(0.163±0.011±0.008)%, B(B0→D1−ℓ+νℓ)×B(D1−→D¯*0π−)=(0.306±0.050±0.029)%, B(B0→D1′−ℓ+νℓ)×B(D1′−→D¯*0π−)=(0.206±0.068±0.025)%, B(B0→D2*−ℓ+νℓ)×B(D2*−→D¯*0π−)=(0.051±0.040±0.010)%, B(B+→D¯10ℓ+νℓ)×B(D¯10→D*−π+)=(0.249±0.023±0.015)%, B(B+→D¯1′0ℓ+νℓ)×B(D¯1′0→D*−π+)=(0.138±0.036±0.009)%, B(B+→D¯2*0ℓ+νℓ)×B(D¯2*0→D*−π+)=(0.137±0.026±0.009)%, B(B0→D1−ℓ+νℓ)×B(D1−→D−π+π−)=(0.102±0.013±0.009)%, B(B+→D¯10ℓ+νℓ)×B(D¯10→D¯0π+π−)=(0.105±0.011±0.009)%, are extracted. This is the first observation of the decays B→D¯1ℓ+νℓ with D1→Dπ+π−.

We present a measurement of the branching fractions of four $B^{0,-}\to D^{(*)+,0} K^- K^{0}_S$ decay modes. The measurement is based on data from SuperKEKB electron-positron collisions at the $\Upsilon(4S)$ resonance collected with the Belle II detector and corresponding to an integrated luminosity of ${362~\text{fb}^{-1}}$. The event yields are extracted from fits to the distributions of the difference between expected and observed $B$ meson energy to separate signal and background, and are efficiency-corrected as a function of the invariant mass of the $K^-K_S^0$ system. We find the branching fractions to be: \[ \text{B}(B^-\to D^0K^-K_S^0)=(1.89\pm 0.16\pm 0.10)\times 10^{-4}, \] \[ \text{B}(\overline B{}^0\to D^+K^-K_S^0)=(0.85\pm 0.11\pm 0.05)\times 10^{-4},\] \[ \text{B}(B^-\to D^{*0}K^-K_S^0)=(1.57\pm 0.27\pm 0.12)\times 10^{-4}, \] \[ \text{B}(\overline B{}^0\to D^{*+}K^-K_S^0)=(0.96\pm 0.18\pm 0.06)\times 10^{-4},\] where the first uncertainty is statistical and the second systematic. These results include the first observation of $\overline B{}^0\to D^+K^-K_S^0$, $B^-\to D^{*0}K^-K_S^0$, and $\overline B{}^0\to D^{*+}K^-K_S^0$ decays and a significant improvement in the precision of $\text{B}(B^-\to D^0K^-K_S^0)$ compared to previous measurements.

- Abstract
The processes e+e−→Σ0Σ¯0 and e+e−→Σ+Σ¯− are studied using initial-state-radiation events in a sample of 980 fb−1 collected with the Belle detector at the KEKB asymmetric-energy e+e− collider. The cross sections from the mass threshold to 3 GeV/c2 and the effective form factors of Σ0 and Σ+ are measured. In the charmonium region, we observe the decays J/ψ→Σ0Σ¯0 and J/ψ→Σ+Σ¯− and determine the respective branching fractions.

- Abstract
Using the data sample of 980 fb−1 collected with the Belle detector operating at the KEKB asymmetric-energy e+e− collider, we present the results of an investigation of the Λπ+ and Λπ− invariant mass distributions looking for substructure in the decay Λc+→Λπ+π+π−. We find a significant signal in each mass distribution. When interpreted as resonances, we find for the Λπ+ (Λπ−) combination a mass of 1434.3±0.6(stat)±0.9(syst) MeV/c2 [1438.5±0.9(stat)±2.5(syst) MeV/c2], an intrinsic width of 11.5±2.8(stat)±5.3(syst) MeV/c2 [33.0±7.5(stat)±23.6(syst) MeV/c2] with a significance of 7.5σ (6.2σ). As these two signals are very close to the K¯N threshold, we also investigate the possibility of a K¯N cusp, and find that we cannot discriminate between these two interpretations due to the limited size of the data sample.

- Abstract
We present a study of a singly Cabibbo-suppressed decay Λc+→pKS0KS0 and a Cabibbo-favored decay Λc+→pKS0η based on 980 fb−1 of data collected by the Belle detector, operating at the KEKB energy-asymmetric e+e− collider. We measure their branching fractions relative to Λc+→pKS0: B(Λc+→pKS0KS0)/B(Λc+→pKS0)=(1.48±0.08±0.04)×10−2 and B(Λc+→pKS0η)/B(Λc+→pKS0)=(2.73±0.06±0.13)×10−1. Combining with the world average B(Λc+→pKS0), we have the absolute branching fractions, B(Λc+→pKS0KS0)=(2.35±0.12±0.07±0.12)×10−4 and B(Λc+→pKS0η)=(4.35±0.10±0.20±0.22)×10−3. The first and second uncertainties are statistical and systematic, respectively, while the third ones arise from the uncertainty on B(Λc+→pKS0). The mode Λc+→pKS0KS0 is observed for the first time and has a statistical significance of >10σ. The branching fraction of Λc+→pKS0η has been measured with a threefold improvement in precision over previous results and is found to be consistent with the world average.

- Abstract
Using (771.6±10.6)×106 BB¯ meson pairs recorded by the Belle experiment at the KEKB e+e− collider, we report the branching fractions B(B¯0→D*+π−)=(2.62±0.02±0.09)×10−3 and B(B¯0→D*+K−)=(2.22±0.06±0.08)×10−4; the quoted uncertainties are statistical and systematic, respectively. A measurement of the ratio of these branching fractions is also presented, RK/π=B(B¯→D*+K−)/B(B¯→D*+π−)=(8.41±0.24±0.13)×10−2, where systematic uncertainties due to the D*+ meson reconstruction cancel out. Furthermore, we report a new QCD factorization test based on the measured ratios for B¯→D*+h− and B¯→D*+ℓ−ν decays at squared momentum transfer values equivalent to the mass of the h=π or K hadron. The parameters |a1(h)| are measured to be |a1(π)|=0.884±0.004±0.003±0.016 and |a1(K)|=0.913±0.019±0.008±0.013, where the last uncertainties account for all external inputs. These values are approximately 15% lower than those expected from theoretical predictions. Subsequently, flavor SU(3) symmetry is tested by measuring the ratios for pions and kaons, |a1(K)|2/|a1(π)|2=1.066±0.042±0.018±0.023, as well as for different particle species. The ratio is consistent with unity and therefore no evidence for SU(3) symmetry breaking effects is found at the 5% precision level.

High Energy Physics - Experiment - Abstract
Using the data sample of 980 fb$^{-1}$ collected with the Belle detector operating at the KEKB asymmetric-energy $e^+e^-$ collider, we present the results of an investigation of the $\Lambda\pi^+$ and $\Lambda\pi^-$ invariant mass distributions looking for substructure in the decay $\Lambda_c^+\rightarrow\Lambda\pi^+\pi^+\pi^-$. We find a significant signal in each mass dis\ tribution. When interpreted as resonances, we find for the $\Lambda\pi^+$ ($\Lambda\pi^-$) combination a mass of $1434.3 \pm 0.6 (\mathrm{stat}) \pm 0.9(\mathrm{syst})$ MeV/$c^2$ [$1438.5 \pm 0.9 (\mathrm{stat}) \pm 2.5(\mathrm{syst})$ MeV/$c^2$], an intrinsic width of $11.5 \pm 2.8 (\mathrm{stat}) \pm 5.3(\mathrm{syst})$ MeV/$c^2$ [$33.0 \pm 7.5 (\mathrm{stat}) \pm 23.6(\mathrm{syst})$ MeV/$c^2$] with a significance of 7.5$\sigma$ (6.2$\sigma$). As these two signals are very close to the $\bar{K}N$ threshold, we also investigate the possibility of a $\bar{K}N$ cusp, and find that \ we cannot discriminate between these two interpretations due to the limited size of the data sample.

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
We present a measurement of the branching fractions of the Cabibbo favored B¯0→D+π- and the Cabibbo suppressed B¯0→D+K- decays. We find B(B¯0→D+π-)=(2.48±0.01±0.09±0.04)×10-3 and B(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 B¯0→D+K- and B¯0→D+π- is measured to be RD=[8.19±0.20(stat)±0.23(syst)]×10-2. These measurements are performed using the full Belle dataset, which corresponds to 772×106BB¯ pairs and use the Belle II software framework for data analysis.

- Abstract
The branching fractions of the decays B+→ηℓ+νℓ and B+→η′ℓ+νℓ are measured, where ℓ is either an electron or a muon, using a data sample of 711 fb−1 containing 772×106BB¯ pairs collected at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e− collider. To reduce the dependence of the result on the form factor model, the measurement is performed over the entire q2 range. The resulting branching fractions are B(B+→ηℓ+νℓ)=(2.83±0.55(stat.)±0.34(syst.))×10−5 and B(B+→η′ℓ+νℓ)=(2.79±1.29(stat.)±0.30(syst.))×10−5.

- Abstract
We report results from the first search for the rare penguin-dominated decay mode B0→KS0KS0γ, 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 BB¯ pairs collected with the Belle detector at the KEKB asymmetric-energy e+e− collider. No statistically significant signals are observed in the KS0KS0 invariant mass range 1 GeV/c2

- Abstract
We search for a new gauge boson Z′ that couples only to heavy leptons and their corresponding neutrinos in the process e+e−→Z′(→μ+μ−)μ+μ−, using a 643 fb−1 data sample collected by the Belle experiment at or near the ϒ(1S,2S,3S,4S,5S) resonances at the KEKB collider. While previous searches for Z′ performed a data-based estimation of the initial state radiation effect, our search for the Z′ is the first to include effects due to initial state radiation in the signal simulated samples that were used in estimating the detection efficiency. No signal is observed in the Z′ mass range of 0.212–10 GeV/c2, and we set an upper limit on the coupling strength, g′, constraining the possible Z′ contribution to the anomalous magnetic dipole moment of the muon.

Physical review letters 127(21), 211801 (1-9) (2021). doi:10.1103/PhysRevLett.127.211801, We report a measurement of the $D^0$ and $D^+$ lifetimes using $D^0$���$K^-��^+$ and $D^+$���$K^-��^+��^+$ decays reconstructed in $e^+e^-$��� $c\overline{c}$ data recorded by the Belle II experiment at the SuperKEKB asymmetric-energy $e^+e^-$ collider. The data, collected at center-of-mass energies at or near the $��$(4S) resonance, correspond to an integrated luminosity of 72 fb$^{-1}$. The results, $��$($D^0$)=410.5��1.1(stat)��0.8(syst) fs and ��($D^+$)=1030.4��4.7(stat)��3.1(syst) fs, are the most precise to date and are consistent with previous determinations., Published by APS, College Park, Md.

- Abstract
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.

- Abstract
We search for a light Higgs boson (A0) 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 158×106 ϒ(2S) events accumulated with the Belle detector at the KEKB asymmetric energy electron-positron collider. No significant A0 signals in the mass range from the τ+τ− or μ+μ− threshold to 9.2 GeV/c2 are observed. We set the upper limits at 90% credibility level (C.L.) on the product branching fractions for ϒ(1S)→γA0 and A0→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)→γA0(→τ+τ−) production. For A0→μ+μ−, the upper limits on the product branching fractions for ϒ(1S)→γA0 and A0→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 sinθA0 are also given.

- Abstract
We present a measurement of the Cabibbo-Kobayashi-Maskawa unitarity triangle angle ϕ 3 (also known as γ) using a model-independent Dalitz plot analysis of B + → D ( K S 0 $$ {K}_S^0 $$ h + h − )h +, where D is either a D 0 or D ¯ $$ \overline{D} $$ 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 ϕ 3 = (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.

- Abstract
We present a measurement of the branching fractions of the Cabibbo favored B¯0→D+π− and the Cabibbo suppressed B¯0→D+K− decays. We find B(B¯0→D+π−)=(2.48±0.01±0.09±0.04)×10−3 and B(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 B¯0→D+K− and B¯0→D+π− is measured to be RD=[8.19±0.20(stat)±0.23(syst)]×10−2. These measurements are performed using the full Belle dataset, which corresponds to 772×106BB¯ pairs and use the Belle II software framework for data analysis.

We measure the photon-energy spectrum in radiative bottom-meson ($B$) decays into inclusive final states involving a strange hadron and a photon. We use SuperKEKB electron-positron collisions corresponding to $189~\mathrm{fb}^{-1}$ of integrated luminosity collected at the $\Upsilon(4S)$ resonance by the Belle II experiment. The partner $B$ candidates are fully reconstructed using a large number of hadronic channels. The $B \rightarrow X_s \gamma$ partial branching fractions are measured as a function of photon energy in the signal $B$ meson rest frame in eight bins above $1.8~\mathrm{GeV}$. The background-subtracted signal yield for this photon energy region is $343 \pm 122$ events. Integrated branching fractions for three photon energy thresholds of $1.8~\mathrm{GeV}$, $2.0~\mathrm{GeV}$, and $2.1~\mathrm{GeV}$ are also reported, and found to be in agreement with world averages., Comment: 14 pages, 3 figures

Using 980 fb−1 of data at and around the Υ(nS) (n=1, 2, 3, 4, 5) resonances collected with the Belle detector at the KEKB asymmetric-energy e+e− collider, the two-photon process γγ→γψ(2S) is studied from the threshold to 4.2 GeV for the first time. Two structures are seen in the invariant mass distribution of γψ(2S): one at MR1=3922.4±6.5±2.0 MeV/c2 with a width of ΓR1=22±17±4 MeV, and another at MR2=4014.3±4.0±1.5 MeV/c2 with a width of ΓR2=4±11±6 MeV; the signals are parametrized with the incoherent sum of two Breit-Wigner functions. The first structure is consistent with the X(3915) or the χc2(3930), and the local statistical significance is determined to be 3.1σ with the systematic uncertainties included. The second matches none of the known charmonium or charmoniumlike states, and its global significance is determined to be 2.8σ including the look-elsewhere effect. The production rates are ΓγγB(R1→γψ(2S))=9.8±3.6±1.3 eV assuming (JPC,|λ|)=(0++,0) or 2.0±0.7±0.2 eV with (2++,2) for the first structure and ΓγγB(R2→γψ(2S))=6.2±2.2±0.8 eV with (0++,0) or 1.2±0.4±0.2 eV with (2++,2) for the second. Here, the first errors are statistical and the second systematic, and λ is the helicity.

Physical review / D 106(1), 012003 (2022). doi:10.1103/PhysRevD.106.012003, We search for a new gauge boson Z′ that couples only to heavy leptons and their corresponding neutrinos in the process e+e−→Z′(→μ+μ−)μ+μ−, using a 643 fb−1 data sample collected by the Belle experiment at or near the Υ(1S,2S,3S,4S,5S) resonances at the KEKB collider. While previous searches for Z′ performed a data-based estimation of the initial state radiation effect, our search for the Z′ is the first to include effects due to initial state radiation in the signal simulated samples that were used in estimating the detection efficiency. No signal is observed in the Z′ mass range of 0.212–10 GeV/c2, and we set an upper limit on the coupling strength, g′, constraining the possible Z′ contribution to the anomalous magnetic dipole moment of the muon., Published by Inst., Melville, NY

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.

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

Physics ,ddc:530 - 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.

Physical review / D 106(1), 012003 (2022). doi:10.1103/PhysRevD.106.012003, We search for a new gauge boson $Z'$ that couples only to heavy leptons and their corresponding neutrinos in the process $e^{+} e^{-} \rightarrow Z'(\rightarrow \mu^{+}\mu^{-}) \mu^{+}\mu^{-}$, using a 643 fb$^{-1}$ data sample collected by the Belle experiment at or near the $\Upsilon(1S,2S,3S,4S,5S)$ resonances at the KEKB collider. For the first time, effects due to initial state radiation are used in estimating the detection efficiency. No signal is observed in the mass range of $0.212-10$ $GeV/{\it c}^2$ and we set an upper limit on the coupling strengh, $g'$, constraining $Z'$ as a possible contributor to the anomalous magnetic dipole moment of muon., Published by Inst., Melville, NY

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

We measure the photon-energy spectrum in radiative bottom-meson ($B$) decays into inclusive final states involving a strange hadron and a photon. We use SuperKEKB electron-positron collisions corresponding to $189~\mathrm{fb}^{-1}$ of integrated luminosity collected at the $\Upsilon(4S)$ resonance by the Belle II experiment. The partner $B$ candidates are fully reconstructed using a large number of hadronic channels. The $B \rightarrow X_s \gamma$ partial branching fractions are measured as a function of photon energy in the signal $B$ meson rest frame in eight bins above $1.8~\mathrm{GeV}$. The background-subtracted signal yield for this photon energy region is $343 \pm 122$ events. Integrated branching fractions for three photon energy thresholds of $1.8~\mathrm{GeV}$, $2.0~\mathrm{GeV}$, and $2.1~\mathrm{GeV}$ are also reported, and found to be in agreement with world averages.

KEK-B ,BELLE ,branching ratio ,GeV - Abstract
We report the first search for the penguin-dominated process $B^0 \rightarrow K_S^0 K_S^0 \gamma$ using the full data sample of $772\times 10^6$$B\bar{B}$ pairs collected with the Belle detector at the KEKB asymmetric-energy $e^+ e^-$ collider. We do not observe any statistically significant signal yield in the $K_S^0$-pair invariant mass range 1 GeV/$c^2 < M_{K_S^0 K_S^0} < $ 3 GeV/$c^2$, and set the following upper limits at 90% confidence level: $\mathcal{B}(B^0 \to K_S^0 K_S^0 \gamma) < 5.8\times10^{-7}$, $\mathcal{B}(B^0 \to f_2 \gamma)\times \mathcal{B}(f_2 (1270) \to K_S^0 K_S^0 ) < 3.1\times10^{-7}$, and $\mathcal{B}(B^0 \to f_2^{\prime} \gamma)\times \mathcal{B}(f_2^{\prime} (1525) \to K_S^0 K_S^0 ) < 2.1\times10^{-7}$. Further, 90% confidence upper limits have also been set in the range of [0.7-2.9]$\times10^{-7}$ on the $B^0 \rightarrow K_S^0 K_S^0 \gamma$ branching fraction in bins of $M_{K_S^0 K_S^0}$.

ddc:530 - 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.

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

ddc:530 - Abstract
We search for a new gauge boson Z′ that couples only to heavy leptons and their corresponding neutrinos in the process e+e−→Z′(→μ+μ−)μ+μ−, using a 643 fb−1 data sample collected by the Belle experiment at or near the Υ(1S,2S,3S,4S,5S) resonances at the KEKB collider. While previous searches for Z′ performed a data-based estimation of the initial state radiation effect, our search for the Z′ is the first to include effects due to initial state radiation in the signal simulated samples that were used in estimating the detection efficiency. No signal is observed in the Z′ mass range of 0.212–10 GeV/c2, and we set an upper limit on the coupling strength, g′, constraining the possible Z′ contribution to the anomalous magnetic dipole moment of the muon.

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.

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 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, Published by IOP, Melville, NY

- Abstract
We present a measurement of the branching fractions of the Cabibbo favored $\overline{B}$$^{0}$ ���D$^{+}$��$^{���}$ and the Cabibbo suppressed $\overline{B}$$^{0}$ ���D$^{+}$K$^{���}$ decays. We find B($\overline{B}$$^{0}$ ���D$^{+}$��$^{���}$)=(2.48��0.01��0.09��0.04)��10$^{���3}$ and B($\overline{B}$$^{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$^{���}$ ��$^{+}$��$^{���}$ branching fraction. The ratio of branching fractions of $\overline{B}$$^{0}$ ���D$^{+}$K$^{���}$ and $\overline{B}$$^{0}$ ���D$^{+}$��$^{���}$ 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.

Physical review / D 105(11), 112011 (2022). doi:10.1103/PhysRevD.105.112011, Using $980~\rm fb^{-1}$ of data on and around the $\Upsilon(nS)(n=1,2,3,4,5)$ resonances collected with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider, the two-photon process $\gamma\gamma\to \gamma\psi(2S)$ is studied from $\sqrt{s} = 3.7$ to $4.2~{\rm GeV}$ for the first time. Evidence is found for a structure in the invariant mass distribution of $\gamma\psi(2S)$ at $M_1 = 3921.3\pm 2.4 \pm 1.6~{\rm MeV}/c^2$ with a width of $\Gamma_1 = 0.0\pm 5.3 \pm 2.0~{\rm MeV}$ and a significance of $4.0\sigma$ including systematic uncertainties, and another structure is seen at $M_2 = 4014.4\pm 4.1 \pm 0.5~{\rm MeV}/c^2$ with a width of $\Gamma_2 = 6\pm 16 \pm 6~{\rm MeV}$ and a global significance of $2.8\sigma$ including the look-elsewhere effect, if the mass spectrum is parametrized with the incoherent sum of two Breit-Wigner functions. The upper limits of the widths are determined to be $\Gamma_1^{\rm UL} = 11.5~{\rm MeV}$ and $\Gamma_2^{\rm UL} = 39.3~{\rm MeV}$ at 90% confidence level. The production rates are determined to be $\Gamma_{\gamma\gamma}{\cal B}(R_1\to\gamma\psi(2S)) = 8.2\pm 2.3\pm 0.9~{\rm eV}$ assuming $(J^{PC}, |\lambda|) =(0^{++}, 0)$ and $1.6\pm 0.5\pm 0.2~{\rm eV}$ with $(2^{++}, 2)$ for the first structure and $\Gamma_{\gamma\gamma}{\cal B}(R_2\to\gamma\psi(2S)) = 5.3\pm 2.7\pm 2.5~{\rm eV}$ with $(0^{++}, 0)$ and $1.1\pm 0.5\pm 0.5~{\rm eV}$ with $(2^{++}, 2)$ for the second one. Here, the first errors are statistical and the second systematic., Published by Inst., Melville, NY
