Revisiting the Annihilation Corrections in Non-leptonic ${\bar{B}}_s^0$ Decays within QCD Factorization

Qin Chang, Xiao-Wei Cui, Lin Han +1

Motivated by the recent measurements of non-leptonic ${\bar{B}}_s^0$ decays by CDF and LHCb collaborations, especially the large $\mathcal{B}({\bar{B}}_s^0\to {\pi }^{+}{\pi }^{-})$, we revisit the hard…
