Measurement of the polarisation of W bosons produced with large transverse momentum in pp collisions at with the ATLAS experiment

This paper describes an analysis of the angular distribution of W→eν and W→μν decays, using data from pp collisions at $$\sqrt{s} = 7\ \mbox{TeV}$$ 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 …
