Determination of the CP violating weak phase γ from the Decays B → D π

الأصل · EN

We propose a new method to extract the CP violating weak phase γ (the phase of Vub*) in the CKM paradigm of the Standard Model, using B- → D⁰ π- → f π- and B- → D⁰ π- → f π- decays, where f are final states such as K+ π-, K+ ρ-, K ππ, etc. We also study the experimental feasibility of our new method. With possibility of new phases in the CKM matrix, we re-examine some of the previously proposed methods to determine γ, and find that it would be in principle possible to identify γ and a new phase angle θ separately.
