CP VIOLATION, MIXING AND LIFETIME RESULTS FROM BABAR
- SLAC
The BABAR collaboration has analyzed 60M B{bar B} pairs collected at the {Upsilon}(4S) resonance at the PEP II asymmetric collider at SLAC. Using this data sample they have measured the CP violation parameters sin(2{beta}) = 0.75 {+-} 0.09{sub STAT} {+-} 0.04{sub SYST} and |{lambda}| = 0.92 {+-} 0.06{sub STAT} {+-} 0.02{sub SYST} from B{sup 0} {yields} c{bar c} + K{sup 0(*)} + c.c. decays. From charmless 2-body B decays they measure A{sub K{pi}} = -0.05 {+-} 0.06 {+-} 0.01(-0.14, +0.05),S{sub {pi}{pi}} = -0.01 {+-} 0.37 {+-} 0.07(-0.66, +0.62), C{sub {pi}{pi}} = -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.
