-corrections to the Drell-Yan process at large
invariant dilepton mass for experiments at CERN Large Hadron
Collider (LHC) have been studied. All formulae for the cross
sections and kinematical constraints are presented in the explicit
form. The FORTRAN code READY for numerical analysis of
Drell - Yan observables in the high energy region and electroweak
radiative correction procedure (reweighting) has been
constructed. The radiative corrections are found to become
significant at high dilepton mass M. The complete corrections at
"bare" setup change the dimuon mass distribution up to 
-5.6% (-15.3%) for M =1 (2) TeV at the LHC energy
and reduce significantly forward-backward asymmetry. The table of
supporting points for reweighting at M = 2TeV has been
calculated.
Key words: Drell - Yan process, large invariant dilepton mass, forward-backward asymmetry
