Improved methods for observing CP violation in B-+/--> KD and measuring the CKM phase gamma - art. no. 036005

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 s tates. It is found that choosing final states which are not CP eigenstates can lead to large direct CP violation which can give significant bounds on gamma without any theoretical assumptions. If two or more modes are studied , gamma may be extracted with a precision on the order of +/- 15 degrees gi ven similar to 10(8) B-mesons. We also discuss the case of three body decay s of the D where additional information may be obtained from the distributi on of the D decay products and consider the impact of D (D) over bar oscill ations.
