| Summary: | We discuss photon-photon fusion mechanisms of dilepton production in
proton-proton collisions with rapidity gap in the main detector and one forward
proton in the forward proton detectors. This is relevant for the LHC
measurements by ATLAS+AFP and CMS+PPS. Transverse momenta of the intermediate
photons are taken into account and photon fluxes are expressed in terms of
proton electromagnetic form factors and structure functions. Both
double-elastic and single-dissociative processes are included in the analysis.
Different parametrizations of the structure functions are used. Some
differential distributions are presented. Some differences with respect to the
results without proton measurement are discussed. |
