Abstract
We present predictions for the diffractive production of χ 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 productions and make 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 χ production, and study background and other scenarios including the contribution of inclusive χ production. The results agree with the Tevatron data and are extrapolated, highlighting the exclusive χ c 0 production at LHC energies. A possible new measurement at the Tevatron using the DØ forward detectors is investigated, taking advantage of the dominance of exclusive production for high enough diffractive mass fraction.
