N2 - We measure the inclusive single muon charge asymmetry and the like-sign dimuon charge asymmetry in pp‾ collisions using the full data set of 10.4  fb−1 collected with the D0 detector at the Fermilab Tevatron. The standard model predictions of the 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 ΔΓd/Γd between the mass eigenstates of the B0 meson system and the semileptonic charge asymmetries adsl and assl of B0 and B0s mesons, respectively.
