Description

We present $W$ boson and lepton charge asymmetry measurements from $W$ decays in the electron channel, with 9.7 fb$^{-1}$ of RunII data collected by the D0 detector at the Fermilab Tevatron Collider. The electron charge asymmetry is presented as a function of the electron transverse momentum and pseudo-rapidity out to $|\eta|\leq 3.2$; we also give the $W$ charge asymmetry as a function of $W$ boson rapidity. The asymmetries are compared with next-to-leading order perturbative quantum chromodynamics calculations. These charge asymmetry measurements will allow more accurate determinations of the proton parton distribution functions.
