Weak Phase γ Using Isospin Analysis and Time Dependent Asymmetry in B d →

چکیده
Abstract We present a method for measuring the weak phase γ using isospin analysis of three body B decays into Kππ channels. Differential decay widths and time dependent asymmetry in Bd → KSπ π mode needs to be measured into even isospin ππ states. The method can be used to extract γ, as well as, the size of the electroweak penguin contributions. The technique is free from assumptions like SU(3) or neglect of any contributions to the decay amplitudes. By studying different regions of the Dalitz plot, it is possible to reduce the ambiguity in the value of γ.

An Analysis of the Time-Dependent CP Asymmetry in B → ππ Decays in the Standard Model
Measurements of the time-dependent CP asymmetry in the decay B d(t) → ππ and its charge conjugate by the BELLE and BABAR collaborations currently yield C ππ = −0.46 ± 0.13 and S ππ = −0.74 ± 0.16, characterizing the direct and mixing-induced CP asymmetries, respectively. We study the implication of these measurements on the CKM phenomenology taking into account the available information in the ...

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-mai...

The contributions of supersymmetric particles in the isospin symmetry violation in B → K * γ decay mode are investigated. The model parameters are adopted from minimal Supergravity with minimal flavor violation. A complete scan of the mSUGRA parameter space has been performed, using the next to leading supersymmetric contributions to the relevant Wilson coefficients. The results are compared to...

Intrigued by a recent Belle result for a large direct CP asymmetry in B → D+D−, we study the effects of a b̄ → ūud̄ quark transition by combining the asymmetry information with rates and asymmetries in isospin-related decays. Using a reasonable hierarchy among several contributions to these decays, including an exchange amplitude which we estimate, we present tests for factorization of the leadin...

We study the isospin asymmetry as an observable in exclusive B→K∗γ decay that can be used to study the effects of physics beyond the Standard Model. We present predictions for isospin asymmetry in Supersymmetric extension of the Standard Model with minimal flavor violation, using parameter values allowed by current experimental constraints. This observable can provide very tight constraints on ...
