摘要
In this contribution we analyze the electromagnetic interactions present in hadron-hadron collisions at the LHC energy. In particular, we summarize our estimate for the total cross sections for the diffractive photoproduction of Z(0) and vector mesons in the h h --> h X h process (X = Z(0), J/psi, Gamma), which are characterized by two rapidity gaps in the final state. The study of these processes is feasible considering the proton tagging detectors (Roman Pots) already planned for the initial start-up of the LHC.
