Description
We discuss production of Drell-Yan massive lepton pairs at hadron colliders in framework of the parton Reggeization approach, which includes off-shell initial state effects by the gauge-invariant way. We compare our results for transverse momentum and rapidity spectra as well as for angular coefficients with existing experimental data and perform predictions for NICA collider at the total energy $\sqrt{S}=24$ GeV. We have found sufficient difference between our calculations, which include off-shell initial state effects, and predictions of conventional TMD factorization approach for helicity structure functions when transverse momenta of lepton pairs are much smaller they invariant masses.
