We present a search for the rare flavor-changing neutral-current decay $B^0 \to K^{\ast 0}\tau^+\tau^-$ with data collected by the Belle II experiment at the SuperKEKB electron-positron collider. The analysis uses a 365  fb$^{−1}$ data sample recorded at the center-of-mass energy of the $\Upsilon(4⁢ ...

We present the result of a search for the charged-lepton-flavor violating decays $\tau^- \to e^{\mp}\ell^{\pm}\ell^-$, where $\ell$ is a muon or an electron, using a data sample with an integrated luminosity of 428 fb$^{-1}$ recorded by the Belle II experiment at the SuperKEKB $e^+e^-$ collider. The ...

We present the first search for the lepton-flavor-violating decay modes $B^0 \to K^0_S\tau^{\pm}\ell^{\mp}(\ell = \mu, e)$ using the 711 and 365 fb$^{-1}$ data samples recorded by the Belle and Belle II detectors, respectively. We use a hadronic $B$-tagging technique to fully reconstruct a $B$ meson ...

We report a determination of the CKM angle ϕ3, also known as γ, from a combination of measurements using samples of up to 711 fb−1 from the Belle experiment and up to 362 fb−1 from the Belle II experiment. We combine results from analyses of B+ → DK+, B+ → Dπ+, and B+ → D*K+ decays, where D is an ad ...

We present the result of a search for the charged-lepton-flavor violating decay τ− → μ−μ+μ− using a 424 fb−1 sample of data recorded by the Belle II experiment at the SuperKEKB e+e− collider. The selection of e+e− → τ+τ− events is based on an inclusive reconstruction of the non-signal tau decay, and ...
