CP Violation and Rare Decays
نویسنده
چکیده
The origin of CP violation is one of the fundamental questions of particle physics. Currently, we know of only two distinct examples of CP violation: the matter-antimatter asymmetry in the universe and CP violation in the neutral kaon system. Although there are several manifestations of CP violation in the neutral kaon system, all of them (with the possible exception of the measurements of = which will be discussed below) can be explained by asymmetric K0 K0 mixing. This mixing results in the KL and KS being states of mixed CP, and is referred to as indirect CP violation. The parameter , which is used to parameterize this e ect, quanti es the CP impurity of the KL and KS states:

متن کاملRare Decays, CP Violation and QCD
We discuss several aspects of rare decays and CP violation in the standard model including the impact of the recent top quark discovery. In particular we review the present status of next-to-leading QCD calculations in this field stressing their importance in the determination of the parameters in the Cabibbo-Kobayashi-Maskawa matrix. We emphasize that the definitive tests of the standard model...

متن کاملCp Violation, Mixing and Rare Decays at the Tevatron Now and in Run Ii I Introduction
We review the status of current B mixing and CP violation measurements from the Fermilab Tevatron. With the existing data sample, the CDF collaboration has made competitive measurements of B 0 d mixing; set limits on B 0 s mixing; and has begun a direct search for CP violation in the B system through the decay B 0 =B 0 ! J==K 0 s. The prospects for future b measurements at the Tevatron, includi...
