Abstract
Inspired by the recent measurements on two-body nonleptonic [Formula: see text] weak decay at BESIII, the charm-changing [Formula: see text] weak decays are studied with perturbative QCD approach, where [Formula: see text] denotes [Formula: see text] and [Formula: see text] vector mesons. It is found that branching ratio for [Formula: see text] decay can reach up to [Formula: see text], which is within the potential measurement capability of the future high-luminosity experiments.
