Title: Central exclusive dijet production at the Fermilab Tevatron

Abstract

We perform a phenomenological analysis of dijet production in double Pomeron exchange at the Tevatron. We find that the CDF-Run I results do not rule out the presence of an exclusive dijet component, as predicted by Khoze, Martin and Ryskin (KMR). With the high-statistics CDF-Run II data, we predict that an exclusive component at the level predicted by KMR may be visible, although the observation will depend on accurate modeling of the inclusive double Pomeron exchange process. We also compare to the predictions of the DPEMC Monte Carlo, which contains a nonperturbative model for the central exclusive process. We show that the perturbative model of KMR gives different predictions for the dijet E{sub T} dependence in the high dijet mass fraction region than nonperturbative models.
