Study of the γ(1S) → DP decays

Inspired by the potential prospects of high-luminosity dedicated colliders and the high enthusiasms in searching for new physics in the flavor sector at the intensity frontier, the gamma(1S) -> D-pi(+), D-0 pi(0) and Ds-K+ weak decays are studied with the perturbative QCD approach. It is found within the standard model that the branching ratios for the concerned processes are tiny, about O(10(-18)), and far beyond the detective ability of current experiments unless there exists some significant enhancements from a novel interaction.

Automated summary

Studied weak decays of gamma(1S) -> D-pi(+), D-0 pi(0), and Ds-K+ using perturbative QCD approach, finding very tiny branching ratios within the standard model, which require significant enhancements from novel interactions for detectability in current experiments.
