Abstract

We present the Forward Physics Monte Carlo (FPMC) designed to simulated central particle production with one or two leading intact protons and some hard scale in the event. The underlying interaction between protons or anti-protons through singlet exchange can manifest itself in many forms. The following production mechanisms are implemented: single diffractive dissociation, double pomeron exchange, and exclusive production due to two-gluon or two-photon exchanges. With increasing beam center-of-mass-energies, the production of new final states become possible at the LHC. The aim of FPMC is to implement these processes in one common framework.
