Determination of the strange-quark density of the proton from ATLAS measurements of the W→ℓν and Z→ℓℓ cross sections

A QCD analysis is reported of ATLAS data on inclusive W ± and Z boson production in pp collisions at the LHC, jointly with ep deep-inelastic scattering data from HERA. The ATLAS data exhibit sensitivity to the light quark sea composition and magnitude at Bjorken x∼0.01. Specifically, the data suppor...
