Charged Particles Pair Production in pp Scattering: Survival Factor and Proton Tagging

Standard Model and hypothetical particles can be produced in photon–photon fusion at the LHC. If protons survive, they can be detected (tagged) in the forward detectors providing unique possibility for the New Physics searches and the Standard Model tests. We present semi-analytical formulas for the fiducial cross sections of such processes. We consider taking into account proton survival probability and briefly discuss contribution from semi-inclusive processes.
