We study the double-diffractive production of various heavy
systems (e.g. Higgs, dijet, and SUSY particles) at LHC
and Tevatron collider energies. In each case we compute the
probability that the rapidity gaps, which occur on either side of
the produced system, survive the effects of soft rescattering and
QCD bremsstrahlung effects. We calculate both the luminosity for
different production mechanisms, and a wide variety of subprocess
cross sections. The results allow numerical predictions to be
readily made for the cross sections of all these processes at the
LHC and the Tevatron collider. For example, we predict that the
cross section for the exclusive double-diffractive
production of a 120 GeV Higgs boson at the LHC is about 3 fb, and
that the QCD background in the
decay mode is about 4
times smaller than the Higgs signal if the experimental
missing-mass resolution is 1 GeV. For completeness we also
discuss production via γγ or WW fusion.
