Abstract
Inspired by the recent measurements on theJ/ψ(1S)→Dsρ,DuK⁎weak decays at BESIII and the potential prospects of charmonium at high-luminosity heavy-flavor experiments, we studyψ(1S,2S)andηc(1S,2S)weak decays into final states including one charmed meson plus one light meson, considering QCD corrections to hadronic matrix elements with QCD factorization approach. It is found that the Cabibbo-favoredψ(1S,2S)→Ds-ρ+,Ds-π+,D¯u0K¯⁎0decays have large branching ratios≳10-10, which might be accessible at future experiments.
