Penguins in CP violating B decays
Michael Gronau
Abstract
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 Bππ 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.
