Study of $B_{c}^{-}$ ${\to}$ $J/ÏÏ^{-}$, $Î·_{c}Ï^{-}$ Decays with QCD Factorization

Abstract

The $B_{c}$ ${\to}$ $J/ÏÏ$, $Î·_{c}Ï$ decays are studied in the scheme of the QCD factorization approach. The branching ratios are calculated with the asymptotic distribution amplitude of the pion. The charm quark mass effect is considered. We find that the mass effect on the branching ratios is small.
