Search for lepton-flavor-violating $\ddot{I}{„}^{-}\to \hat{I}{¼}^{-}\hat{I}{¼}^{+}\hat{I}{¼}^{-}$ 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 $\ddot{I}{„}^{-}\to \hat{I}{¼}^{-}\hat{I}{¼}^{+}\hat{I}{¼}^{-}$ using a $424f{b}^{-1}$ sample of data recorded by the Belle II experiment at t…
