Branching ratio and CP asymmetry of $B_s\to {\pi }^{+}{\pi }^{-}$ decays in the perturbative QCD approach

Ying Li, Cai-Dian Lu, Zhen-Jun Xiao +1

In this paper, we calculate the decay rate and CP asymmetry of the $B_s\to {\pi }^{+}{\pi }^{-}$ decay in perturbative QCD approach with Sudakov resummation. Since none of the quarks in final s…
