Search for lepton-flavor-violating ${\tau }^{-}\to {\ell }^{-}{K}_s^0$ decays at Belle and Belle II

Belle, Belle II Collaborations, : +419

We present the results of a search for charged-lepton-flavor violating decays ${\tau }^{-}\to {\ell }^{-}{K}_S^0$, where ${\ell }^{-}$ is either an electron or a muon. We combine $e…
