| dc.description | Various strategies for extracting or constraining the weak phase gamma with controlled theoretical uncertainties are reviewed. Measurements of the rates for the hadronic decays B^+- -> pi K provide largely model-independent information on gamma. Hadronic uncertainties enter only at the level of nonfactorizable contributions to the decay amplitudes that are power-suppressed in Lambda/m_b and, simultaneously, violate SU(3) flavor symmetry or are doubly Cabibbo suppressed. In addition, these decays have a rich potential for probing physics beyond the Standard Model. Alternative proposals for learning gamma are also discussed briefly. | |
