### Measurement of the CP-violation parameter of B0 mixing and decay with pp̄→μμX data

Abstract:

We measure the dimuon charge asymmetry A in pp̄ collisions at a center of mass energy s=1960GeV. The data was recorded with the D0 detector and corresponds to an integrated luminosity of approximately 1.0fb-1. Assuming that the asymmetry A is due to asymmetric B0↔B̄0 mixing and decay, we extract the CP-violation parameter of B0 mixing and decay: ( B0)1+| B0|2=AB04=-0.0023±0.0011(stat)±0.0008(syst).AB0 is the dimuon charge asymmetry from decays of B0B̄0 pairs. The general case, with CP violati...
