Two Gluon Exchange Model Predictions for Double Pomeron Jet Production

Abstract

I extend the two gluon exchange picture of elastic scattering, known as the Low-Nussinov or Subtractive Quark Model, to predict cross sections for double pomeron exchange processes. In particular, I calculate p p-bar to p p-bar q q-bar where the q q-bar partons appear as jets separated from the final p and p-bar by large gaps in rapidity. The predicted cross section is large enough that this process should be observable at the Fermilab Tevatron and at the Large Hadron Collider. It can be distinguished from the background of ordinary jet production by the absence of particles produced in the gap regions.
