Abstract

We propose a new method to extract the CP-violating weak phase gamma (the phase of V-ub(*)) in the CKM paradigm of the standard model, using B- --> D(0)pi (-) --> f pi (-) and B- --> (D) over bar (0)pi (-) --> f pi (-) decays, where the f's are final states such as K(+)pi (-), K(+)rho (-), K pi pi,etc. We also study the experimental feasibility of our new method. With the possibility of new phases in the CKM matrix, ve re-examine some of the previously proposed methods to determine gamma, and find that it would be in principle possible to identify gamma and a new phase angle theta separately.
