High precision single-differential W+- - boson production cross-sections as a function of electron or muon transverse momentum pT or their pseudorapity eta, as well as double-differential cross-sections as functions of these variables, are measured in proton–proton collisions at centre-of-mass energies root s = 5.02 TeV and 13 TeV. The W-boson charge asymmetry as a function of lepton eta is also measured. The data, collected in dedicated runs at reduced instantaneous luminosity with the ATLAS detector at the Large Hadron Collider, correspond to integrated luminosities of 255 pb−1 at 5.02 TeV and 338 pb−1 at 13 TeV. The measurements are in agreement with Standard-Model predictions calculated at next-to-next-to-leading-order in the strong coupling constant alpha_s including transverse-momentum resummation at next-to-next-to-leading logarithmic accuracy using several parton distribution functions. The impact of the measured differential cross-sections as a function of lepton eta on the determination of these functions is studied using a profiling technique.

Abstract

High precision single-differential W+- - boson production cross-sections as a function of electron or muon transverse momentum pT or their pseudorapity eta, as well as double-differential cross-sections as functions of these variables, are measured in proton–proton collisions at centre-of-mass energies root s = 5.02 TeV and 13 TeV. The W-boson charge asymmetry as a function of lepton eta is also measured. The data, collected in dedicated runs at reduced instantaneous luminosity with the ATLAS detector at the Large Hadron Collider, correspond to integrated luminosities of 255 pb−1 at 5.02 TeV and 338 pb−1 at 13 TeV. The measurements are in agreement with Standard-Model predictions calculated at next-to-next-to-leading-order in the strong coupling constant alpha_s including transverse-momentum resummation at next-to-next-to-leading logarithmic accuracy using several parton distribution functions. The impact of the measured differential cross-sections as a function of lepton eta on the determination of these functions is studied using a profiling technique.
