Determination of weak phases φ 2 and φ 3 from B → ππ , Kπ in the pQCD method
نویسنده
چکیده
We look at methods to determine the weak phases φ2 and φ3 from B → ππ and Kπ decays within the perturbative QCD approach. We obtain quite interesting bounds on φ2 and φ3 from experimental measurement in B-factory: 55 ≤ φ2 ≤ 100 and 51 ≤ φ3 ≤ 129. Specially we predict the possibility of large direct CP violation effect in B → ππ (23± 7%) decay. DPNU-02-28 hep-ph/0209002

Recent data of two-body nonleptonic B meson decays allow a topological-amplitude analysis up to the O(λ2) accuracy, where λ denotes the Wolfenstein parameter. We find an exact solution from the B → ππ data and an exact solution from the B → Kπ data, which satisfy the approximate SU(3) flavor symmetry. These solutions indicate that the color-suppressed tree amplitude is large, all other amplitud...

متن کاملOf D - Meson Dalitz Plot Analyses
The formalism of Dalitz-Plot analysis is reviewed in the preceding note. Recent studies of multi-body decays of charm mesons probe a variety of physics including γ/φ 3 , D 0 –D 0 mixing, searches for CP violation, doubly Cabibbo-suppressed decays, and properties of S-wave ππ, Kπ, and KK resonances. In the following, we discuss: (1) D 0 → K 0 S π + π − ; (2) doubly Cabibbo-suppressed decays; and...
متن کاملDirect CP Violation and Final State Interactions in Hadronic B Decays
Although mixing-induced CP violation in B decays has been observed in the golden mode B → J/ψKS for several years, a first confirmed observation of direct CP asymmetry was not established until recently in the charmless B decays B 0 (B) → Kπ by both BaBar [1] and Belle [2]. Also the combined BaBar and Belle measurements of B 0 → ρπ imply a 3.6σ direct CP asymmetry in the ρπ mode [3]. As for dir...
