摘要

Abstract

Motivated by the measurements on Br(B- 0s → π- K * +)and Br(B- 0s → K± K * )by LHCb collabo‐ration ,aχ2‐fit on the parameters XAi ,f was performed within QCD factorization (QCDF) framework .The ob‐servables of Bs → PV decays were calculated and analyzed by considering the end‐point parameters gotten from Bu ,d → PV as input parameters .It was found that the universalities of XAi ,f (PV ) for the Bu ,d ,s → PV decay modes were allowed ,the theoretical results of Br(B- 0s → K * +π-) and Br(B- 0s → K ± K * ) were corresponding with the LHCb data ,and the pure annihilation decays B
