Direct 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 کاملMeasurements of CP violation in the three-body phase space of charmless B decays
The violation of CP symmetry is well established experimentally in the quark sector and, in the Standard Model (SM), is explained by the Cabibbo-KobayashiMaskawa [1] matrix through the presence of a single irreducible complex phase. Although the SM is able to describe all CP asymmetries observed experimentally in particle decays, the amount of CP violation within the SM is insufficient to expla...
متن کاملCharming penguin and direct CP-violation in charmless B decays
In the study of two-body charmlessB decays as a mean of looking for direct CP-violation and measuring the CKM mixing parameters in the Standard Model, the short-distance penguin contribution with its absorptive part generated by charm quark loop seems capable of producing sufficient B → Kπ decays rates, as obtained in factorization and QCD-improved factorization models. However there are also l...
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...
