摘要：

The BaBar collaboration has analysed 60M B (B) over bar pairs. collected at the T(4S) resonance at the PEP II asymetric collider at SLAC. Using this data sample we have measured the CP violation parameters sin(2beta) = 0.75+/-0.09(STAT) +/- 0.04(SYST) and \lambda\ = 0.92 +/- 0.06(STAT) +/- 0.02(SYST) from B-0 --> c (c) over bar + K-0(*) + c.c. decays. From charmless 2-body B decays we measure A(Kpi) = -0.05 +/- 0.06 +/- 0.01(-0.14, +0:05), S-pipi = -0.01 +/- 0.37 +/- 0.07(-0.66, +0;62), C-pipi = -0.02 +/- 0.29 +/- 0.07(-0.54, +0.48). A number of B lifetime and mixing parameters, extracted from subsamples of this data, set, axe also presented.
