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 recently measured the branching fraction of the $B^+ \to K^+\nu\bar{\nu}$⁢ decay using 362  fb$^{-1}$ of on-resonance $e^+e^-$ collision data under the assumption of Standard Model kinematics, providing the first evidence for this decay. To facilitate future reinterpretations and maximize the sci ...

We present a study of the rare charm meson decays $D^0 \to K^+K^-e^+e^-, \pi^+\pi^-e^+e^-$, and $K^-\pi^+e^+e^-$ using a 942 fb$^{-1}$ dataset collected by the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. We identify $D^0$ candidates via the charge of the pion from $D^{\ast +} \to ...
