Study of CP-violating charge asymmetries of single muons and like-sign dimuons in p(p)over-bar collisions

Original language description

We measure the inclusive single muon charge asymmetry and the like-sign dimuon charge asymmetry in p (p) over bar collisions using the full data set of 10.4 fb(-1) collected with the D0 detector at the Fermilab Tevatron. The standard model predictions ofthe charge asymmetries induced by CP violation are small in magnitude compared to the current experimental precision, so nonzero measurements could indicate new sources of CP violation. The measurements differ from the standard model predictions of CP violation in these asymmetries with a significance of 3.6 standard deviations. These results are interpreted in a framework of B meson mixing within the Cabibbo-Kobayashi-Maskawa formalism to measure the relative width difference Delta Gamma(d)/Gamma(d) between the mass eigenstates of the B-0 meson system and the semileptonic charge asymmetries a(sl)(d) and a(sl)(s) of B-0 and B-s(0) mesons, respectively.
