Abstract
We measure the inclusive single muon charge asymmetry and the like-sign dimuon charge asymmetry in
p

p
collisions using the full data set of
10.4
fb

collected with the D0 detector at the Fermilab Tevatron. The standard model predictions of the charge asymmetries induced by
C
P
violation are small in magnitude compared to the current experimental precision, so nonzero measurements could indicate new sources of
C
P
violation. The measurements differ from the standard model predictions of
C
P
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
