Study of $Î¥(nS)$ ${\to}$ $B_{c}P$ decays with perturbative QCD approach

Abstract

With the potential prospects of the $Υ(nS)$ at high-luminosity dedicated heavy-flavor factories, the color-favored $Υ(nS)$ ${\to}$ $B_{c}π$, $B_{c}K$ weak decays are studied with the pQCD approach. It is found that branching ratios for the $Υ(nS)$ ${\to}$ $B_{c}π$ decay are as large as the order of ${\cal O}(10^{-11})$, which might be measured promisingly by the future experiments.
