Current Issues in CP Violation
نویسنده
چکیده
A brief review of CP violation in K and B decays is given. While the observables ε and Re(ε/ε) describing CP violation in neutral K decays do not allow a powerful test of the CKM mechanism of CP violation, rare K → πνν decays and in particular the B-meson system are much more promising in this respect. After a brief look at the K system, selected aspects of CP-violating effects in B decays are discussed. It is pointed out that combined branching ratios for B → πK modes, which have been observed recently by the CLEO collaboration, may allow to derive stringent constraints on the CKM angle γ that could open a window to new physics.

متن کاملTheoretical Review on CP Violation in Rare B decays
We discuss several issues related to direct CP violation in rare B meson decays. We review the use of CP asymmetries in extracting information of strong and weak phases, how the experimental data fit into the overall picture, and the current status of the Kπ puzzle. We also examine the flavor symmetry assumption using closely related decay modes and extract the weak phase γ from certain B → K∗π...
متن کاملTwo Lectures on FCNC and CP Violation in Supersymmetry ∗
These two lectures constitute a reappraisal and an update of the status of the Flavour Changing Neutral Current (FCNC) and CP violation issues in supersymmetry. The first lecture discusses these points in the framework of the Minimal Supersymmetric Standard Model (MSSM), while the second one provides an analysis in a generic low-energy supersymmetric extension of the Standard Model. The goal of...
متن کاملTesting non-standard CP violation in neutrino propagation
Non-standard physics which can be described by effective four fermion interactions may be an additional source of CP violation in the neutrino propagation. We discuss the detectability of such a CP violation at a neutrino factory. We assume the current baseline setup of the international design study of a neutrino factory (IDS-NF) for the simulation. We find that the CP violation from certain n...
