Diffractive physics: from the Tevatron to the LHC
Michele Gallinaro
Abstract
Measurements of soft and hard diffractive processes have been performed at the Tevatron p-pbar collider during the past decade. Diffractive events are studied by means of identification of one or more rapidity gaps and/or a leading antiproton. Here, results are discussed within the Tevatron data and compared to those obtained at the HERA ep collider. The traditional ``pomeron'' is described within the framework of QCD and the issues discussed include pomeron structure, diffractive cross section factorization, and universality of rapidity gap formation. Exclusive dijet and low-mass state production in double-pomeron exchange processes, including predictions for Higgs production at the LHC from dijet measurements at the Tevatron.
