Weak Matrix Elements for Cp Violation *
We present preliminary results of matrix elements of four fermion operators relevant to the determination of ǫ and ǫ ′ /ǫ using staggered fermions.
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 کاملWeak 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 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 ...

I review several topics pertaining to Weak decays of b and c quarks, including measurements of |V cb |, |V ub /V cb |, f Ds and b → sγ.
