AFP is a project to extend the diffractive physics programme of the ATLAS
experiment by installing new detectors that will be able to tag forward protons
scattered at very small angles. This will allow us to study Single Diffraction,
Double Pomeron Exchange, Central Exclusive Production and photon-photon
processes. This note presents the physics case for the AFP project and briefly
describes the proposed detector system.Comment: 10 pages, 8 figures, presented at the Cracow Epiphany Conference on
