Query: CP Violation, Mixing and Lifetime Results from BaBar   The BaBar collaboration has analysed 60M BB_ pairs collected at the Upsilon
(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 B0 to
cc_+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, are also presented.
