A recent measurement by the D0 Collaboration, of the charge asymmetry of muons in W→μν events is discussed. Using 4.9 fb-1 of data collected by the D0 detector, the muon charge asymmetry, A(η), where η is the muon pseudorapidity, is measured inclusively and in two bins of muon transverse momentum, \ptmu. After being corrected for background contamination and detector effects (resolution and acceptance), the data are compared to NLO QCD predictions with CTEQ 6.6 PDFs. For inclusive \ptmu, reasonable agreement is observed. However, the prediction fails to describe the data in bins of \ptmu. In most η bins, the data are more precise than the predictions, and will provide tight constraints on future PDFs.
