An improved measurement of the CP-violation parameters in decays based on a 140 fb-1 data sample was presented. One neutral B meson was reconstructed in one of the specified decay channels. Results show that there is a large CP-violating phase in its decay amplitude. It was also observed that the CP asymmetry in the decay differs from the standard model expectation by 3. 5 standard deviations.
