Searches for charged-lepton-flavor violation in $χ_{b J} (1 P)$ decays

Belle, Belle II Collaborations, : +425

We report the first searches for charged-lepton-flavor violation in decays of $χ_{b J} (1 P)$ ( $J = 0, 1,$ and $2$ ) to a pair of charged leptons using 158 million $Υ (2 S)$ decays collect…
