Abstract

The CP violation parameters in B⁰→π⁺π^- decay were measured. The result for S_ππ indicated that mixing-induced CP violation is large. The large A_ππ term is an indication of direct CP violation in B meson decay, and suggests that there is a large hadronic phase and interference between the tree and penguin amplitudes. In this case the precise determination of sin2φ₂ from S_ππ requires additional measurements including the branching fractions for the decays B⁰→π⁰π⁰.

N2 - The CP violation parameters in B0→π+π- decay were measured. The result for Sππ indicated that mixing-induced CP violation is large. The large Aππ term is an indication of direct CP violation in B meson decay, and suggests that there is a large hadronic phase and interference between the tree and penguin amplitudes. In this case the precise determination of sin2φ2 from Sππ requires additional measurements including the branching fractions for the decays B0→π0π0.
