Abstract
The LHCb Collaboration has reported for the first time the branching fraction for the decay as . They measured the branching fraction of this decay relative to that of the normalization channel as . In this work, we have studied the and decays in three scales of μ and strong coupling values mesons using a simple model based on the framework of the factorization approach presented. We have obtained for decay at and for decay at . We have also estimated at which is consistent with the experimental result.
