Searches for charged-lepton-flavor violation in ${\chi }_{bJ}(1P)$ decays

Belle, Belle II Collaborations, : +415

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