Abstract

Various methods are discussed for obtaining the CKM angle gamma through the interference of the charged B-meson decay channels B--->(K-D0) and B--->K-(D) over bar (0) where the D-0 and (D) over bar (0) decay to common final states. It is found that choosing final states which are not CP eigenstatescan lead to large direct CP violation which can give significant bounds ongamma without any theoretical assumptions. If two or more modes are studied, gamma may be extracted with a precision on the order of +/- 15 degrees given similar to 10(8) B-mesons. We also discuss the case of three body decays of the D where additional information may be obtained from the distribution of the D decay products and consider the impact of D (D) over bar oscillations.
