Experimental results in diffractive processes are summarized and
a few notable characteristics described in terms of Quantum Chromodynamics.
Exclusive dijet production is used to establish a benchmark for future
experiments in the quest for diffractive Higgs production at the Large
Hadron Collider. Using new data from the Tevatron and dedicated diffractive
triggers, no excess over a smooth falling distribution for exclusive dijet
events could be found. Stringent upper limits on the exclusive dijet
production cross section are presented. The quark/gluon composition of
dijet final states is used to provide additional hints on exclusive dijet
production.
