Description
We discuss production of Drell-Yan lepton pairs at hadron colliders
in the framework of the Parton Reggeization Approach, which includes
off-shell initial state effects in a gauge-invariant way. Other
possible prescriptions to restore gauge-invariance of
hard-scattering coefficient with off-shell initial-state partons are
also investigated and significant differences for the resulting
structure functions are found, especially for the
E-288 collaboration (
agreement. Also we perform predictions for the Drell-Yan structure
functions at NICA
