Description
We present an improved measurement of the charge asymmetry $A$ of like-sign
dimuon events in 9 fb$^{-1}$ of $p\overline{p}$ collisions recorded with the
D0 detector at a center-of-mass energy $\sqrt{s} = 1.96$ TeV at the
Fermilab Tevatron collider. From $A$, we extract the like-sign dimuon
charge asymmetry in semileptonic $b$-hadron decays. We also study the
dependence of charge asymmetry on muon impact parameter. Additional constraints
on the $CP$ violation in the $B$ meson sector are also derived from a measurement
of the flavor-specific semileptonic asymmetry in the $B^0_d\to\mu D+X$ channel.
