Direct CP Violation In B → π + π − V With ρ 0 − ω Mixing Effects : Phenomenological Approach

We present a detailed study of direct CP violation and branching ratios in the channels B0,± → π+π−V 0,±, where V is a vector meson (K∗0,± or ρ). Emphasis is placed upon the important role played by ρ0 −ω mixing effects in the estimation of the CP -violating asymmetry parameter, acp, associated with the difference of B and B̄ decay amplitudes. A thorough study of the helicity amplitudes is prese...

Cp Violation in B 0 → Π + Π − Decay T. Nakadaira

We present an improved measurement of CP-violating asymmetries in B 0 → π + π − decays based on a 78 fb −1 data sample collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e + e − collider. We reconstruct one neutral B meson as a B 0 → π + π − CP eigenstate and identify the flavor of the accompanying B meson from its decay products. From the asymmetry in the di...
