Abstract (data abstract)
Fermilab-Tevatron. Measurement of the muon charge asymmetry from the decay of the $W$ boson via W to mu nu using 7.3 fb$^{-1}$ of integrated luminosity collected with the D0 detector at the Fermilab Tevatron Collider at sqrt(s) = 1.96 TeV. The muon charge asymmetry is presented in two kinematic regions in muon transverse momentum and event missing transverse energy: $(p^{\mu}_{T} > 25$ GeV, $E_T^{missing} > 25$ GeV) and $(p^{\mu}_{T} > 35$ GeV, $E_T^{missing} > 35$ GeV). The measured asymmetries are compared with theory predictions made using three parton distribution function sets. The predictions do not describe the data well for $p^{\mu}_{T} > 35$ GeV, $E_T^{missing} > 35$ GeV, and larger values of muon pseudorapidity.
