Kavli Affiliate: T. Higuchi | First 5 Authors: Belle, Belle II Collaborations, :, I. Adachi, K. Adamczyk | Summary: We present the first search for the lepton flavor-violating decay modes $B^0 rightarrow K_S^0 tau^pm ell^mp~(ell=mu, e)$ using the 711 fb$^{-1}$ and 365 fb$^{-1}$ data samples recorded by the Belle and Belle II detectors, respectively. We […]
