Study Of Nonleptonic B_s^*?M₁M₂?M=D,D_s,?,K? Weak Decays With Factorization Approach

Particle physics is a subject which studies the interaction and transformation law of the basic particles.The Standard Model of particle physics is a successful theory based on the gauge theory and to describe the strong,weak and electromagnetic interaction of elementary particles.The heavy flavor physics,such as beauty and charm physics,offers an important tool to test the Standard Model?SM?,explore the source of CP violation and search for the indirect hints of new physics at the low energy scale.Thanks to the fruitful running of B factories?Ba Bar and Belle?and Tevatron?CDF and D0?in the past years,most of B meson decay modes with branching fractions????(10^-7)are well measured,which provides a fertile ground for theoretical study.Especially,some interesting and important phenomena are observed,such as the measured direct CP violation in B system,the “?K and ?? puzzles",CP violating effects related to B_s-??? mixing and so on.With the running LHCb and upgrading Super KEKB/Belle-?,the experimental analysis of the heavy flavor physics will be pushed towards new frontiers of precision.Therefore,besides of B meson,some rare weak decay modes of the other heavy mesons,such asB^*1 and B_s^* mesons?J^P=1^-?et al.,are expected to be observed in the near future.In the past years,because B_s^* meson decay occur mainly through radiative processesB_S^*?B?S?^? and their weak decays are generally much rare,there are few theoretical studies ofB_s^* weak decays before.While,because of the rapid development of experiment as just mentioned,the detailed theoretical studies of*?s?B rare decays are in fact worthwhile then.Recently,some semileptonicB_C^* meson decays are evaluated with QCD sum rules,in which the branching fractions of the order8o?10?-are predicted.Compared with theB_C^* system,B_u,d,s^* meson decays are much easier to be measured by future Belle-II experiment due to the fact that the production fractionsu,d,sf are generally much larger thancf.So,theB_u,d,s^* meson rare decays are much worthier of being studied.In this paper,we will pay our attention to the nonleptonic B_s^*?M₁M₂?M=D,D_s,?,K? decays.
