Observation of $B \to D^{(*)} K^{-} K_{S}^{0}$ decays using the 2019-2022 Belle II data sample

Belle II Collaboration, F. AbudinÃ©n, I. Adachi +575

We present a measurement of the branching fractions of four $B^{0, -} \to D^{(*) +, 0} K^{-} K_{S}^{0}$ decay modes. The measurement is based on data from SuperKEKB electron-positron colli…

First Measurement of $R (X_{I ¨ / ℓ})$ as an Inclusive Test of the $b \to c I ¨ I^½$ Anomaly

Belle II Collaboration, I. Adachi, K. Adamczyk +390

We measure the tau-to-light-lepton ratio of inclusive $B$ -meson branching fractions $R (X_{I ¨ / ℓ}) \equiv B (B \to X I ¨ I^½) / B (B \to X ℓ I^½)$ , where $ℓ$ indi…

Search for lepton-flavor-violating $I ¨ ^{-} \to ℓ^{-} I ¨ $ decays in 2019-2021 Belle II data

We report a search for lepton-flavor-violating decays $I ¨ ^{-} \to ℓ^{-} I ¨ $ ( $ℓ^{-} = e^{-}, I^¼^{-}$ ) at the Belle II experiment, using a sample of electron-positron data produced at the…

A test of light-lepton universality in the rates of inclusive semileptonic $B$ -meson decays at Belle II

Belle II Collaboration, L. Aggarwal, H. Ahmed +349

We present the first measurement of the ratio of branching fractions of inclusive semileptonic $B$ -meson decays, $R(X_{e/Î¼}) = \mathcal{B}(B\to X \, e \, Î½) / \mathcal{B}(B\to X…
