Study of $J/\ddot{I}ˆ$ $\to$ $D_{s,d}V$ decays with perturbative QCD approach

Abstract

Inspired by the recent measurements on two-body nonleptonic $J/\ddot{I}ˆ$ weak decay at BESIII, the charm-changing $J/\ddot{I}ˆ$ $\to$ $D_{s,d}V$ weak decays are studied with perturbative QCD approach, where $V$ denotes $\ddot{I}$ and $K^{\ast }$ vector mesons. It is found that branching ratio for $J/\ddot{I}ˆ$ $\to$ $D_s\ddot{I}$ decay can reach up to $\mathcal{O}(10^{-9})$, which is within the potential measurement capability of the future high-luminosity experiments.
