Improving the Drell–Yan probe of small x partons at the LHC via an azimuthal angle cut
Abstract Predictions for Drell–Yan lepton pair production at low dilepton mass and small x at the LHC usually have a large scale dependence. This can be decreased by determining an optimal factorization scale. In this paper, we reduce this scale by imposing a cutoff in azimuthal angle between the tr...

Abstract Predictions for Drell–Yan lepton pair production at low dilepton mass and small x at the LHC usually have a large scale dependence. This can be decreased by determining an optimal factorization scale. In this paper, we reduce this scale by imposing a cutoff in azimuthal angle between the transverse momentum of the leptons, properly taking into account Sudakov effects. This allows one to probe the parton distributions at smaller scales eliminating most of the current theoretical uncertainty. |
