CP violation in B decays and supersymmetry
نویسندگان
چکیده
CP violation in hadronic B-decays is studied in a definite and well motivated framework for flavour physics and supersymmetry. Possible deviations from the standard model both in mixing and in decay amplitudes are discussed. An attempt is made to describe an experimental strategy for looking at these deviations and for measuring the relevant parameters.

Cp Violation -a New Era
We give a pedagogical review of the theory of CP violation with emphasis on the implications of recent experimental results. The review includes: (i) A detailed description of how CP violation arises in the Standard Model and in its extension that allows for neutrino masses; (ii) The formalism of CP violation in meson decays and its application to various K decays (ε K , ε ′ /ε and K → πνν), D ...
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...
متن کاملOn Gaugino Contributions to Soft Leptogenesis
We study the contributions to CP violation in right-handed sneutrino decays induced by soft supersymmetry-breaking gaugino masses including flavour effects and paying special attention to the role of thermal corrections. Using a field-theoretical as well as a quantum mechanical approach we compute the CP asymmetries and we conclude that for all the soft-supersymmetry breaking sources of CP viol...
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 کاملCP Violation In and Beyond the Standard Model
The special features of CP violation in the Standard Model are presented. The significance of measuring CP violation in B, K and D decays is explained. The predictions of the Standard Model for CP asymmetries in B decays are analyzed in detail. Then, four frameworks of new physics are reviewed: (i) Supersymmetry provides an excellent demonstration of the power of CP violation as a probe of new ...
