Transverse momentum dependence of the T -even hadronic structure functions in the Drell-Yan process
Year: 2024
Type: article
Abstract: We present detailed analysis of the T -even lepton angular distribution in the Drell-Yan process including γ / Z 0 gauge boson exchange and using perturbative QCD based on the collinear factorization scheme at leading order in the α s expansion. We focus on the study of the transverse momentum Q T dependence of the corresponding hadronic structure functions and angular coefficients up to next-to-next-to-leading order in the Q T 2 / Q 2 expansion. We analyze Q T dependence numerically and compare T -even angular coefficients integrated over rapidity with available data of the ATLAS Collaboration at LHC. Additionally, we present our results for the forward-backward asymmetry and compare it with data. Published by the American Physical Society 2024
