Search for lepton-flavor-violating $I ¨ ^{-} \to I^¼^{-} I^¼^{+} I^¼^{-}$ decays at Belle II

Belle II Collaboration, I. Adachi, L. Aggarwal +429

We present the result of a search for the charged-lepton-flavor violating decay $I ¨ ^{-} \to I^¼^{-} I^¼^{+} I^¼^{-}$ using a $424 f b^{- 1}$ sample of data recorded by the Belle II experiment at t…
