Weak radiative corrections to Drell-Yan process for large invariant mass of di-lepton pair

The weak radiative corrections to Drell-Yan process above the Z-peak have been studied. The compact asymptotic expression for the two heavy boson exchange - one of significant contributions to the investigated process - has been obtained. The results expand in the powers of the Sudakov electroweak l...

description The weak radiative corrections to Drell-Yan process above the Z-peak have been studied. The compact asymptotic expression for the two heavy boson exchange - one of significant contributions to the investigated process - has been obtained. The results expand in the powers of the Sudakov electroweak logarithms. The numerical analysis in the high energy region is performed. To simulate the detector acceptance we used the standard CMS cuts. It has been ascertained that the considered radiative corrections become large at high di-lepton mass M and increase the di-lepton mass distribution up to 8 % and the forward-backward asymmetry up to 1.4 % at LHC energies and M > 1 TeV. The results can be used for the necessities of future LHC experiments.
