Abstract
Double diffractive Higgs production at pp (or 
)
colliders continues to attract
attention as a potential signal in the search for the boson. We present improved perturbative
QCD estimates of the event rates for both the exclusive and inclusive double diffractive
Higgs processes, paying particular attention to the survival probability of the rapidity gaps.
We find that the major uncertainty is in the prediction for the survival probability associated
with soft rescattering. We show that an analogous process, the double diffractive production
of a pair of jets with large values of ET, has an event rate which makes it accessible at the
Tevatron. Observation of this process can therefore be used as a luminosity monitor for
two-gluon exchange processes, such as the production of a Higgs boson with rapidity gaps on
either side.
