Direct CP Violation in B Decays
We discuss several aspects of direct CP asymmetries in B decays, which are very useful in spite of hadronic uncertainties in asymmetry calculations. 1) Asymmetries in decays to D(∗)K(∗), π+π−, ρ+ρ−, providing precision tests for the CKM phase γ. 2) Null tests in B+ → J/ψK+, π+π0, where a nonzero asymmetry provides evidence for New Physics. 3) Isospin and broken flavor SU(3) relations among CP a...
متن کاملDirect CP Violation In Radiative B Decays
We discuss the role of the radiative B decays B → Xs/d γ in our search for new physics focusing on the issue of direct CP violation. We discuss in some detail a SM prediction for the CP asymmetries in inclusive b → s/d transitions, namely | ∆B (B → Xsγ)+ ∆B (B → Xdγ) |∼ 1 · 10−9. Any measured value in significant deviation of this estimate would indicate new sources of CP violation beyond the C...
متن کاملDirect CP Violation in Charmless B Decays
We report the updated results of direct CP violation measurements from Belle and BaBar for the following modes: B → h+h−/h±π0, B → η( )h± and B → K±π±π∓, where h stands for a charged kaon or pion. The data used in these studies are up to 386 million BB̄ pairs for Belle and 232 million BB̄ pairs for BaBar. The current significant measurements include: ACP (B → K +π−) = −0.108 ± 0.016, ACP (B → ρ 0...
متن کاملCP Violation in B decays with ρ 0 − ω Mixing
A complete study of the processes B → ππV (V = 1−−) is performed both in the framework of the helicity formalism and the effective lagrangian approach. Emphasis is put on the factorization hypothesis and the importance of the ρ−ω mixing in enhancing the direct CP violation. New results involving some branching ratios and the ratio of the Penguin/Tree amplitude are given in details. 1 Physical M...
متن کاملImplications of Charmless B Decays with Large Direct CP Violation
Based on the most recent data in charmless B decays including the very recently reported large direct CP violations, it is shown that the weak phase γ can well be extracted without two-fold ambiguity even only from two decay modes ππ and πK, and its value is remarkably consistent with the global standard model fit at a compatible accuracy. A fit to all the ππ, πK data favor both large electrowe...
