In particular I will discuss diffractive jet production and the possibility of searching for the higgs boson using diffraction at the LHC; the dipole picture of diffraction and saturation; and those processes where a large momentum is transferred across the rapidity gap, for which there has been recent progress both experimentally and theoretically.14 pages.
