Measurement of the weak phase alpha from B0 --> a1(1260)+- pi-+ decays
Abstract
We present the measurement, performed by the BABAR Collaboration, of the weak phase alpha from the time dependent CP asymmetries in B0--> a1(1260)+- pi-+ decays. The model error induced by penguin contributions to the B0 --> a1(1260)+- pi-+ channel is estimated from an SU(3) analysis of the branching fractions of B--> a1(1260) K, B--> K1(1270) pi, and B--> K1(1400) pi decays.
