Double Diffractive Dijet/Higgs Hadroproduction

We consider the pomeron-pomeron fusion mechanisms for the double diffractive production of a Higgs boson or large E_T dijet. We determine the suppression of the ‘rapidity gap’ pomeron-pomeron fusion events due to QCD radiative effects. In particular we use leading log techniques to estimate the cross sections for both exclusive and inclusive double-diffractive Higgs production at LHC energies. The same approach is applied to the double-diffractive central production of large E_T dijets.
