Remarks on Diffractive Production of the Higgs Boson
  Central diffractive production of the Higgs boson has recently received much attention as a potentially interesting production mode at the LHC. We shall review some of the wishes and realities encountered in this field. Theoretical open problems of diffractive dynamics are involved in making accurate predictions for the LHC, among which the most crucial is understanding factorization breaking in hard diffraction.
