Probabilities of rapidity gaps in high energy interactions.

Kaidalov, A. B. and Khoze,, V. A. and Martin, A. D. and Ryskin, M. G. (2001) 'Probabilities of rapidity gaps in high energy interactions.', European physical journal C., 21 (3). pp. 521-529.

Abstract

We show that high energy hadronic reactions which contain a rapidity gap and a hard subprocess have a specific dependence on the kinematic variables, which results in a characteristic behaviour of the survival probability of the gap. We incorporate this mechanism in a two-channel eikonal model to make an essentially parameter-free estimate of diffractive dijet production at the Tevatron, given the diffractive structure functions measured at HERA. The estimates are in surprising agreement with the measurements of the CDF collaboration. We briefly discuss the application of the model to other hard processes with rapidity gaps.
