Study of the ${\Upsilon}(1S)$ ${\to}$ $DP$ decays
2021
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 ${\Upsilon}(1S)$ ${\to}$ $D^{-}{\pi}^{+}$, $\overline{D}^{0}{\pi}^{0}$ and $D_{s}^{-}K^{+}$ 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 ${\cal O}(10^{-18})$, and far beyond the detective ability of current experiments unless there exists some significant enhancements from a noval interaction.
