This paper presents measurements of the W + → μ + ν and W − → μ − ν cross-sections and the associated charge asymmetry as a function of the absolute pseudorapidity of the decay muon. The data were collected in protonproton collisions at a centre-of-mass energy of 8 TeV with the ATLAS experiment at the LHC and correspond to a total integrated luminosity of 20.2 fb −1 . The precision of the crosssection measurements varies between 0.8 and 1.5% as a function of the pseudorapidity, excluding the

The results are compared with predictions based on next-to-next-to-leadingorder calculations with various parton distribution functions and have the sensitivity to discriminate between them.
