Gaps between Jets in the high energy limit

    Research output: Contribution to journalArticlepeer-review


    We use perturbative QCD to calculate the parton level cross section for the production of two jets that are far apart in rapidity, subject to a limitation on the total transverse momentum Q0 in the interjet region. We specifically address the question of how to combine the approach which sums all leading logarithms in Q/Q0 (where Q is the jet transverse momentum) with the BFKL approach, in which leading logarithms of the scattering energy are summed. This paper constitutes progress towards the simultaneous summation of all important logarithms. Using an ''all orders'' matching, we are able to obtain results for the cross section which correctly reproduce the two approaches in the appropriate limits. © SISSA 2005.
