نویسنده
چکیده
The role of penguin amplitudes in CP violating B decays is reviewed, emphasizing recent progress in the analysis of electroweak penguin contributions. It is shown how these terms are included in a model-independent manner when measuring the weak phase α in B → ππ using isospin symmetry, and when determining the phase γ from B → Kπ applying flavor SU(3). Uncertainties due to rescattering effects in B → Kπ are discussed. Invited talk presented at the 17th International Workshop on Weak Interactions and Neutrinos, Cape Town, South Africa, January 24−3

Measurements of the rates for the hadronic decays B ± → πK along with the CP-averaged B ± → π ± π 0 branching ratio can be used to bound and extract the weak phase γ = arg(V * ub). Using preliminary CLEO data, we obtain the bounds |γ| > 93 • at 1σ, and |γ| > 71 • at 90% CL.

This is a quick review of CP non-conservation in B physics. Several methods are described for testing the Kobayashi-Maskawa single phase origin of CP violation in B decays, pointing out some limitations due to hadronic uncertainties. A few characteristic signatures of new physics in B decay asymmetries are listed. Invited talk given at the 1999 Chicago Conference on Kaon Physics Chicago, IL, Ju...

Lepton flavor violating decays Z → µτ and J/Ψ, Υ → µτ are considered. It is shown that these decays can reach sizeable magnitudes if some specific lepton-flavor violating 4-fermion operators are generated by low scale quantum gravity effects, or by some other new physics at a TeV scale.
