We measure the dimuon charge asymmetry $A$ in $p\overline{p}$ collisions at a center of mass energy $\sqrt{s}=1960\text{ }\text{ }\mathrm{GeV}$. The data was recorded with the D0 detector and corresponds to an integrated luminosity of approximately $1.0\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$. Assuming that the asymmetry $A$ is due to asymmetric ${B}^{0}\ensuremath{\leftrightarrow}{\overline{B}}^{0}$ mixing and …
