Muon Pair Production in Radiative Decays of Heavy Quarkonia

Abstract

Muon pair production in exclusive radiative decays ${\chi }_{cJ}\to J/\psi \mu \mu$, ${\chi }_{bJ}\to {\rm Y}\mu \mu$ are considered. We present numerical values of the branching fractions and distributions over various kinematical variables.
