Description
We study the determination of γ from CP-violating observables in B→π+π- and B→ψKS. This determination requires theoretical input to one combination of hadronic parameters. We show that a mild assumption about this quantity may allow bounds to be placed on γ, but we stress the pernicious effects that an eightfold discrete ambiguity has on such an analysis. The bounds are discussed as a function of the direct (C) and interference (S) CP-violating observables obtained from time-dependent B→π+π- decays, and their behavior in the presence of new physics effects in B-B-bar mixing is studied
