Diffractive Production at the Tevatron and the LHC

Abstract

We present predictions for the diffractive production of mesons in the central rapidity region usually covered by collider detectors. The predicted cross sections are based on the Bialas-Landshoff formalism for both exclusive and inclusive production and makes use of the DPEMC Monte-Carlo simulation adapted with kinematics appropriate for small-mass diffractive production. We compare generator-level results with a CDF measurement for exclusive production, and study background and other scenarios including the contribution of inclusive production. The results agree with the Tevatron data and are extrapolated, highlighting the exclusive production at LHC energies. A possible new measurement at the Tevatron using the Dforward detectors is investigated, taking advantage of the dominance of exclusive production for high enough diffractive mass fraction.
