Description
Charged lepton flavour violating processes are unobservable in the standard model, but they are predicted to be enhanced in several new physics extensions. We present the results of a search for $\Upsilon(2{\mathrm{S}})$ and $\Upsilon(3{\mathrm{S}})$ decays to $e^{\pm}\mu^{\mp}$ decays.
The search was conducted using data samples consisting of 99 million $\Upsilon(2{\mathrm{S}})$ and 122 million $\Upsilon(3{\mathrm{S}})$ mesons, collected at center-of-mass energies of 10.23 and 10.36~GeV, respectively, by the BABAR detector at the SLAC PEP-II $e^+e^-$ collider
