| description | A QCD analysis is reported of ATLAS data on inclusive W[superscript ±] 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 support the hypothesis of a symmetric composition of the light quark sea at low x. The ratio of the strange-to-down sea quark distributions is determined to be 1.00[subscript -0.28][superscript +0.25] at absolute four-momentum transfer squared Q[superscript 2]=1.9 GeV[superscript 2] and x=0.023. |
