CepGen – A generic central exclusive processes event generator for hadron-hadron collisions

Description

We present an event generator for the simulation of central exclusive processes in hadron-hadron reactions. Among others, it implements the two-photon production of lepton pairs previously introduced in LPAIR. As a proof of principle, we show that the two approaches are numerically consistent. The k_T-factorized description of this process is also handled, along with the two-photon production of a quark, or a W^+- gauge boson pair. This toolbox may be used as a common framework for the definition of many other processes following this approach. Additionally, photoproduction and other photon induced processes are also considered, or being implemented.
