CP Violation in B Decays and the CKM Matrix
نویسنده
چکیده
Results by the BaBar and Belle experiments of the measurements sin 2α, sin 2β and sin(2β + γ) along with the CKM matrix elements Vcb and Vub are presented. The BaBar and Belle experiments b → scc̄ results for sin 2β are in good agreement with each other, comfortably establishing CP violation within B decays. However, there is a 3.5 standard deviation between this result and sin 2β measured by the Belle experiment using B → φK S decays. Belle also find evidence for CP violation through time dependent measurements of the decay B → ππ, whilst a tighter constraint has been placed on the unitarity angle α by BaBar, using time dependent studies of the decay B → ρρ .

متن کاملDetermining the quark mixing matrix from CP-violating asymmetries.
If the Standard Model explanation of CP violation is correct, then measurements of CP-violating asymmetries in B meson decays can in principle determine the entire quark mixing matrix. According to the Standard Model (SM), CP violation arises from the fact that in the Cabibbo-Kobayashi-Maskawa (CKM) quark mixing matrix, some of the elements are not real. This picture of CP violation will be inc...
متن کاملCp Violation : the Future of B Physics
The subject of CP violation in B decays is reviewed in the Standard Model (SM) and beyond the SM. The present explanation of CP violation in terms of phases in the Cabibbo-Kobayashi-Maskawa (CKM) matrix can be tested through a variety of CP asymmtries in neutral and charged B decays. SM constraints on the CKM phases are violated by new mechanisms of CP nonconservation beyond CKM. Different mech...
متن کاملM. Neubert: Theory of CP Violation in the B-Meson System (LP01) THEORY OF CP VIOLATION IN THE B-MESON SYSTEM
The phenomenon of CP violation is one of the most intriguing aspects of modern physics, with far-reaching implications for the microscopic world as well as for the macrocosmos. CP violation means that there is a fundamental difference between the interactions of matter and anti-matter, which in conjunction with the CPT theorem implies a microscopic violation of time-reversal invariance. CP viol...
