Theory of CP Violation
CP violation in K and B decays is reviewed in the Standard Model (SM) and beyond the SM. In K decays, one is seeking first evidence for CP violation in direct K -+ ~rTr decays. This would not give a precise quantitative test for the present explanation of CP violation in terms of a phase in the Cabibbo-Kobayashi-Maskawa (CKM) matrix. Such tests are provided by a variety of CP asymmetries in neu...
متن کاملTheory - Weak Cp Violation
Given the varied backgrounds of the members of this audience this talk will be a grab bag of topics related to the general theme of CP Violation. I do not have time to dwell in detail on any of them.l First, for the astronomers and astrophysicists among you, I want to begin by reviewing the experimental status of evidence for CP violation in particle processes. There is only one system where th...
متن کاملHeterotic string backgrounds and CP violation
In the framework of ZN orbifolds, we discuss effects of heterotic string backgrounds including discrete Wilson lines on the Yukawa matrices and their connection to CP violation.
متن کاملTheory of CP Violation in B Decays
Theory of CP violation in B decays is reviewed. For CP asymmetries in B” decays, the general formalism is given; the relations with the angles of the unitarity triangle are derived; the sensitivity to new physics is discussed and effects of specific models are described. For CP asymmetries in B* decays, the possible mechanisms are described and the difficulties of theoretical estimation are dis...
متن کاملRecent Developments in Theory of CP Violation
Four topics in theory of CP violation are reviewed. (a) CP violation in B decays: We describe a new clean way of constraining the angle γ of the unitarity triangle and how new CP violation in decay amplitudes can signal new physics. (b) CP violation inK decays: We explain the special features of the decay KL → π νν̄ both as a measurement of Standard Model CP violating parameters and as a probe o...
