Description
Rates of lepton-flavor violation in charged lepton decays are enhanced in many beyond-the-standard-model theories. The low-background samples of $e^+e^- \to \tau^+\tau^-$ events collected by Belle and Belle II allow world-leading searches for such decays with tau leptons. We present results for the decays $\tau \to \ell V^0$, where $V^0$ is a neutral vector meson, $\tau\to\ell \gamma$, and $\tau \to 3\mu$.
