Description
We present the measurements of forward-backward charge asymmetry $A_{FB} $ in
$p\bar{p}\rightarrow Z/\gamma^{*} \rightarrow \mu^+\mu^- $ events using $9.7 \ $fb$^{-1}$ of $ p\bar p$ data collected at $\sqrt s=1.96\ $TeV by the D0 detector at the Fermilab Tevatron collider. $A_{FB}$ is measured as a function of the invariant mass of the dimuon system to extract the effective weak mixing angle $\sin^2\theta^{lep}_{eff}$. In the context of the standard model, using the on-shell renormalization scheme where $\sin^2\theta_W = 1 - M_W^2/M_Z^2$, measurements of $\sin^2\theta^{lep}_{eff}$ yield indirect extractions of the W mass. The result will contribute to the final Tevatron combination of the weak mixing angle and indirect $m_{W}$ measurements.
