Measurement of the W Boson Charge Asymmetry in the Electron Decay Channel

We present a measurement of W boson production charge asymmetry in $p\bar{p}$ collisions as measured in W$\to$e$\nu$ decays. We use 1fb$^{-1}$ data collected with the D0 detector. Theoretical predictions made using CTEQ and MRST Parton Distribution Functions are compared with the measurement.
