Search for charged lepton flavor violating decays of ${\rm Y}(1S)$

Belle Collaboration, S. Patra, V. Bhardwaj +216

We present a search for the charged lepton-flavor-violating decays ${\rm Y}(1S)\to \ell {\ell }^{\prime }$ and radiative charged lepton-flavour-violating decays $Υ(1S)\rightarrowγ\ell\el…
