Diffraction at HERA, the Tevatron and the LHC

Abstract

In these lectures, we present and discuss the most recent results on inclusive diffraction from the HERA and Tevatron colliders and give the prospects for the future at the LHC. Of special interest is the exclusive production of Higgs boson and heavy objects ($W$, top, stop pairs) which will require a better understanding of diffractive events and the link between $ep$ and hadronic colliders, as well as precise measurements and analyses of inclusive diffraction at the LHC in particular to constrain further the gluon density in the pomeron.
