Adachi I, Aggarwal L, Ahmed H, Aihara H, Akopov N, Aloisio A, et al.
Phys Rev Lett . 2025 Feb; 134(1):011802. 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....

Kovalenko E, Adachi I, Aihara H, Asner D, Aushev T, Ayad R, et al.
Phys Rev Lett . 2025 Jan; 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...

Prim M, Bernlochner F, Metzner F, Aihara H, Asner D, Aushev T, et al.
Phys Rev Lett . 2024 Oct; 133(13):131801. PMID: 39392959
We measure the complete set of angular coefficients J_{i} for exclusive B[over ¯]→D^{*}ℓν[over ¯]_{ℓ} decays (ℓ=e, μ). Our analysis uses the full 711  fb^{-1} Belle dataset with hadronic tag-side reconstruction....

Adachi I, Aggarwal L, Aihara H, Akopov N, Aloisio A, Al Said S, et al.
Phys Rev Lett . 2024 Sep; 133(10):101804. 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...

Guan Y, Schwartz A, Kinoshita K, Adachi I, Aihara H, Al Said S, et al.
Phys Rev Lett . 2024 Sep; 133(8):081801. 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...

Phys Rev Lett . 2024 Aug; 133(7):071802. PMID: 39213574
We report the results of the first search for B^{-} decays to the Ξ[over ¯]_{c}^{0}Λ[over ¯]_{c}^{-} final state using 711  fb^{-1} of data collected at the ϒ(4S) resonance with the...

Phys Rev Lett . 2024 Jun; 132(21):211804. 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...

Pharmazie . 2024 Jan; 78(11):245-250. PMID: 38178284
Magnesium oxide is widely used for treating opioid-induced constipation, a serious analgesic-associated problem. Opioid analgesic users are often prescribed non-steroidal anti-inflammatory drugs, which are sometimes combined with acid suppressants to...

Phys Rev Lett . 2023 Dec; 131(21):211802. PMID: 38072609
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...

The first simultaneous determination of the absolute value of the Cabibbo-Kobayashi-Maskawa matrix element V_{ub} using inclusive and exclusive decays is performed with the full Belle data set at the ϒ(4S)...
