$J/{\psi}$ ${\to}$ $DP$, $DV$ decays in the QCD factorization approach

TL;DR

This paper estimates the branching ratios of nonleptonic $J/\psi$ decays into $DP$ and $DV$ final states using QCD factorization, predicting some decays with potentially detectable rates at future experiments.

Contribution

It provides the first quantitative estimates of $J/\psi$ nonleptonic decay branching ratios considering QCD radiative corrections within the factorization framework.

Findings

Certain decay modes have branching ratios ${\gtrsim} 10^{-10}$.

Predicted decays may be detectable in upcoming experiments.

QCD factorization effectively estimates nonleptonic $J/\psi$ decays.

Abstract

Motivated by the recent measurements on nonleptonic $J/{\psi}$ weak decays at BESIII and the potential prospects of $J/{\psi}$ meson at the high-luminosity heavy-flavor experiments, the branching ratios of the two-body nonleptonic $J/{\psi}$ ${\to}$ $DP$, $DV$ decays are estimated quantitatively by considering the QCD radiative corrections to hadronic matrix elements with the QCD factorization approach. It is found that the Cabibbo favored $J/{\psi}$ ${\to}$ $D_{s}^{-}{\rho}^{+}$, $D_{s}^{-}{\pi}^{+}$, $\overline{D}_{u}^{0}\overline{K}^{{\ast}0}$ decays have branching ratios ${\gtrsim}$ $10^{-10}$, which might be promisingly detectable in the near future.
