Measurement of the W charge asymmetry in the W→μν decay mode in pp collisions at √s=7 TeV with the ATLAS detector
This Letter reports a measurement of the muon charge asymmetry from W bosons produced in proton–proton collisions at a centre-of-mass energy of 7 TeV with the ATLAS experiment at the LHC. The asymmetry is measured in the W→μν decay mode as a function of the muon pseudorapidity using a data sample co...
