Study The Decay Of B_s~0??~0?~0 With Perturbative QCD Approach

The most successful model for the results of unified physical theory in the microcosm of the world is the Standard Mode of the particle physics which contains a weak and quantum color dynamics,B physics research is in the standard model calculation.B Physics can test the standard model and be useful for the discovery of new physics.So,since the start for studying B physics,B physics always has been one of the hot area in theoretical physics research.The United States and Japan have constructed laboratories of B physics to study from the view of experimental and has already collected a lot of valid data.As one of the three main goals of today's largest Large Hadron Collider(LHC)is to do a more accurate test of the standard model and the meta-taste physics(mainly B Physics and Charm Physics),and Japan are will to establish laboratory B to do research in recent years.So we believe that it is a good time to do B physical research.In the study of B physical,we notice that as an important component of the B physical Bs0??0?0 has no definite experimental value in the experiment but only has a range,Recently there are many scholars have already recalculated the decay.so we recalculate the decay path,hoping to get a best theoretical calculation in the current theoretical framework before a more accurate result from the experiment.In this paper,we use the perturbation QCD factor to calculate the branch ratio of the decay path of Bs0??0?0.and corresponding CP damage This article is divided into three parts,the first part is a introduction introduce the theoretical framework used in the calculation,do some simple introduction for the framework of some important theories such as standard model,Cabibbo-Kobayashi-Maskawa(CKM)matrix,CP damage and then to the CP destruction,Su Dakov factor The second part is to give the process based on the above theory,gives the specific process of decaying its own calculation,analytic expression,and gives the calculation results.The third part is based on the results of calculations and compared with other already calculated results and gives a summary and outlook for the decay.
