Measurement of CP asymmetries and branching-fraction ratios for B^± → DK^± and Dπ^± with D → \( {K}_{\textrm{S}}^0 \) K^±π^∓ using Belle and Belle II data

We measure CP asymmetries and branching-fraction ratios for B^± → DK^± and Dπ^± decays with D → K ...

Search for lepton-flavor-violating τ decays into a lepton and a vector meson using the full Belle data sample

Charged-lepton-flavor-violation is predicted in several new physics scenarios. We update the analysis of τ lepton decays into a light charged lepton (ℓ = e^± or μ^±) and a vector meson (V⁰ = ρ⁰, ϕ, ω, K^*0, or ...

Combined analysis of Belle and Belle II data to determine the CKM angle ϕ₃ using B⁺ → D( \( {K}_S^0 \) h⁺h⁻)h⁺ decays

We present a measurement of the Cabibbo-Kobayashi-Maskawa unitarity triangle angle ϕ₃ (also known as γ) using a model-independent Dalitz plot analysis of B⁺ → D (

Search for lepton-flavor-violating tau-lepton decays to ℓγ at Belle

Charged lepton flavor violation is forbidden in the Standard Model but possible in several new physics scenarios. In many of these models, the radiative decays τ^± → ℓ^±γ (ℓ = e, μ) are predicted to have a sizeable...
