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.
