Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, L. Aggarwal, H. Aihara, N. Akopov | Summary: We present the result of a search for the charged-lepton-flavor violating decay $tau^- to mu^-mu^+mu^-$ using a $424fb^{-1}$ sample of data recorded by the Belle II experiment at the SuperKEKB $e^{-}e^{+}$ collider. The selection […]
