Off-shell initial state effects, gauge invariance and angular distributions in the Drell–Yan process
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 in...
