Description
Drell-Yan dilepton production is a unique reaction which offers high sensitivity to the parton distribution in the hadron, being an important reference process from both experimental and theoretical points of view. Motivated by recent analyses, where forward Drell--Yan production in proton-proton collisions at the LHC has been studied in the high-energy factorization framework, we improve the calculation by introducing an unintegrated gluon density from a fit to combined HERA data at small values of Bjorken x. This gluon density was calculated within the BFKL formalism in the next-to-leading logarithmic accuracy. We show that it generates a good description of the forward Drell-Yan cross section dependence on the invariant mass of the lepton pair both for LHCb and ATLAS data.
