Abstract

We discuss the mechanism of dilepton production in proton-proton scattering\nvia fusion of virtual photons with identification of one proton on either side.\nThis is relevant for the ATLAS+AFP and CMS+PPS at the LHC. Transverse momenta\nof the photons are taken into account via photon unintegrated fluxes. The\nlatter ones are expressed in terms of proton electromagnetic form factors and\nstructure functions. We include different categories of such processes (double\nelastic, single dissociative). Some differential distributions are shown\nexplicitly and differences with respect to the results without proton\nidentification are discussed. A soft gap survival factor is calculated using\nSuperChic-4 code.\n
