PMID: 39913692
We report measurements of time-dependent CP asymmetries in B^{0}→K_{S}^{0}π^{0}γ decays based on a data sample of (388±6)×10^{6} BB[over ¯] events collected at the ϒ(4S) resonance with the Belle II detector....

133(26):261901.
PMID: 39879008
We report the first evidence for the h_{b}(2P)→ϒ(1S)η transition with a significance of 3.5 standard deviations. The decay branching fraction is measured to be B[h_{b}(2P)→ϒ(1S)η]=(7.1_{-3.2}^{+3.7}±0.8)×10^{-3}, which is noticeably smaller than...

PMID: 39303229
We present the results of a search for the b→dℓ^{+}ℓ^{-} flavor-changing neutral-current rare decays B^{+,0}→(η,ω,π^{+,0},ρ^{+,0})e^{+}e^{-} and B^{+,0}→(η,ω,π^{0},ρ^{+})μ^{+}μ^{-} using a 711 fb^{-1} data sample that contains 772×10^{6} BB[over ¯] events. The...

PMID: 39241732
We present a comprehensive study of B^{0}→ωω decays using 772×10^{6} BB[over ¯] pairs collected with the Belle detector at the KEKB e^{+}e^{-} collider. This process is a suppressed charmless decay...

PMID: 38856254
We measure the tau-to-light-lepton ratio of inclusive B-meson branching fractions R(X_{τ/ℓ})≡B(B→Xτν)/B(B→Xℓν), where ℓ indicates an electron or muon, and thereby test the universality of charged-current weak interactions. We select events...

We report on a search for a heavy Majorana neutrino in the decays τ^{-}→π^{-}ν_{h}, ν_{h}→π^{±}ℓ^{∓}, ℓ=e, μ. The results are obtained using the full data sample of 988 fb^{-1} collected...

We report the first search for a nonstandard-model resonance decaying into τ pairs in e^{+}e^{-}→μ^{+}μ^{-}τ^{+}τ^{-} events in the 3.6-10 GeV/c^{2} mass range. We use a 62.8 fb^{-1} sample of e^{+}e^{-}...

We present the first measurement of the ratio of branching fractions of inclusive semileptonic B-meson decays, R(X_{e/μ})=B(B→Xeν)/B(B→Xμν), a precision test of electron-muon universality, using data corresponding to 189 fb^{-1} from...
