Weak Phases and CP Violation
Time-dependent CP asymmetries in B decays from interference of B-B 0 mixing and b → cc̄s, uūd, sqq̄, and direct asymmetries from interference of b → cūs and b → uc̄s are studied, improving errors in the weak phases β and γ to ±1◦ and ±7◦, respectively. Two kinds of tests for New Physics are discussed: 1. Deviations of asymmetries in b → sqq̄ decays from sin 2β sin∆mt. 2. Violation of a sum rule for...
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 کاملPhases and Cp Violation in Susy
We discuss CP violation in supersymmetric theories and show that CP phenomena can act as a probe of their origins, i.e., compactification and spontaneous supersymmetry breaking. CP violation as a probe of the flavor structure of supersymmetric theories is also discussed. A brief overview is given of several low energy phenomena where CP phases can produce new effects. These include important CP...
متن کاملLarge Phases and Cp Violation in Susy
A brief overview is given of recent developments in the analyses of large phases and CP violation in supersymmetric unified models. The problem of experimental electric dipole moment constraints and large phases is discussed. Implications of large phases on supersymmetric phenomena are reviewed. The possibility of generating a muon electric dipole moment much larger than implied by the scaling ...
متن کاملWeak Hamiltonian , CP Violation and Rare Decays ∗
These lectures describe in detail the effective Hamiltonians for weak decays of mesons constructed by means of the operator product expansion and the renormalization group method. We calculate Wilson coeffcients of local operators, discuss mixing of operators under renormalization, the anomalous dimensions of operators and anomalous dimension matrices. We elaborate on the renormalzation scheme ...
