Forward physics at the LHC

We discuss opportunities for forward physics at the LHC. We start with the classical forward physics topics, such as total arid elastic cross sections and general diffraction. Then we discuss the so called 'new forward physics' topics. The forward physics program at the LHC presently contains the following topics: soft and hard diffraction, parton saturation, BFKL/CCFM dynamics, proton structure, multi-parton scattering, disoriented chiral condensates, incoherent pion emission, centauro events, forward energy and particle flows/minimum bias event structure, two-photon interactions and peripheral collisions, forward physics in pA and AA collisions, and QED processes to determine the luminosity to O(1%) e.g. pp rightward arrow ppee, pp rightward arrow ppmumu.
