A new method for extracting the weak phase γ from B →
نویسنده
چکیده
A new method to extract the weak phase γ is suggested by exploiting B → DK(∗) decay modes that are not Cabibbo suppressed, using the isospin relations, and ignoring the annihilation diagram as usual. Assuming 3× 108BB̄ pair at B factories, one can determine γ with 3− σ accuracy for 80 ∼ γ ∼ 150 using B → DK modes and for 50 ∼ γ ∼ 170 using B → DK∗ modes. ∗e-mail : [email protected] †e-mail : [email protected]

We explore the possibility of extracting the weak phase γ from pure tree decays Λb → Λ(D0,D0,D0 CP ) in a model independent way. The CP violating weak phase γ can be determined cleanly, without any hadronic uncertainties, as these decay modes are free from the penguin pollutions. Furthermore, neither tagging nor time dependent studies are required to extract the angle γ with these modes. Typese...

We propose a new method to extract the CP violating weak phase γ (the phase of V ∗ ub) in the CKM paradigm of the Standard Model, using B − → D0π− → fπ− and B− → D̄0π− → fπ− decays, where f are final states such as K+π−, K+ρ−, Kππ, 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 met...

We describe a new method for extracting weak, CP-violating &Dmacr;phase information, with no hadronic uncertainties, from an angular analysis of B-->V1V2 decays, where V1 and V2 are vector mesons. The quantity sin (2)(2beta+gamma) can be cleanly obtained from the study of decays such as B(0)(d)(t)-->D*+/-rho(-/+), D(*+/-)a(-/+)(1), D(;) *0K(;) (*0), etc. Similarly, one can use B(0)(s)(t)-->D(*+...
