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.

The One

We will attempt to understand the ΔI=1/2 pattern of the nonleptonic weak decays of the kaons. The calculation scheme employed is the Strong Coupling Expansion of lattice QCD. Kogut-Susskind fermions are used in the Hamiltonian formalism. We will describe in detail the methods used to expedite this calculation, all of which was done by computer algebra. The final result is very encouraging. Even though an exact interpretation is clouded by the presence of irrelevant operators, and questions of lattice artifacts, a signal of the ΔI=1/2 rule appears to be observable. With an appropriate choice of the one free parameter, enhancements greater than those observed experimentally can be obtained. We also point out a number of surprising results which we turn up in the course of the calculation.
