The ATLAS Forward Physics Program

After a brief review of the approved ATLAS forward detector system we describe the main ATLAS forward physics program. This program currently includes such topics as soft and hard diffraction, double pomeron exchange, central exclusive production, rapidity gap survival, two photon physics, the determination of the total cross-section and the determination of the absolute luminosity A possible high luminosity upgrade program involving new forward proton detectors is also briefly reviewed. This program opens up a new vista of forward physics for ATLAS that includes SM/MSSM/NMSSM Higgs boson studies, W pair production, slepton production and gluino pair production, etc.
