Abstract
We present a measurement of the muon charge asymmetry from the decay of the boson via using of integrated luminosity collected with the D0 detector at the Fermilab Tevatron Collider at . The muon charge asymmetry is presented in two kinematic regions in muon transverse momentum and event missing transverse energy: (, ) and (, ). The measured asymmetries are compared with theory predictions made using three parton distribution function sets. The data at , , and larger values of favor an increased ratio at higher values of than is predicted.
