Abstract
We propose a new variable, Rj, in order to identify exclusive double-diffractive high ET dijet production. The variable Rj is calculated using the transverse energy ET and pseudorapidity of the jet with the largest ET. For a purely exclusive event the value of Rj -> 1, if we were to neglect hadronisaton and the detector resolution effects. To illustrate the expected Rj-distribution we also compute exclusive three-jet production; and, moreover, include jet smearing effects. By studying the predictions as a function of the size of the rapidity interval, delta(eta), which allows for additional gluon radiation, one can probe the QCD radiation effects which are responsible for the Sudakov suppression of the exclusive amplitude. In this way we may check, and improve, the formalism used to predict the cross sections of exclusive double-diffractive Higgs boson (and/or other New Physics) production.
