N2 - This paper describes an analysis of the angular distribution of W→eν and W→μν decays, using data from pp collisions at s√=7 TeV recorded with the ATLAS detector at the LHC in 2010, corresponding to an integrated luminosity of about 35 pb−1. Using the decay lepton transverse momentum and the missing transverse momentum, the W decay angular distribution projected onto the transverse plane is obtained and analysed in terms of helicity fractions f 0, f L and f R over two ranges of W transverse momentum (pWT):3550 GeV . Good agreement is found with theoretical predictions. For pWT>50 GeV , the values of f 0 and f L−f R, averaged over charge and lepton flavour, are measured to be: f 0=0.127±0.030±0.108 and f L−f R=0.252±0.017±0.030, where the first uncertainties are statistical, and the second include all systematic effects.
