One-loop electroweak radiative corrections to dilepton production in hadron collisions via photon fusion for the Large Hadron Collider (LHC) experimental programme are estimated, with a focus on hard bremsstrahlung. The reaction follows the Drell-Yan process. Studying it is a relevant task of the LHC experimental programme. Detailed numerical analysis of electroweak radiative effects to observable quantities (cross sections and forward-backward asymmetry) in wide kinematical region including the CMS LHC experiment in Run3/HL regime corresponding ultra-high energies and dilepton invariant masses is performed.
