Gaps between Jets in the High Energy Limit
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 whic...
متن کاملEnergy Flow and Rapidity Gaps Between Jets in Photoproduction
Data from the H1 detector at HERA have been used to study photoproduction events which have two or more jets. The data were taken in 1996 and correspond to an integrated luminosity of 6.63 pb−1. Events were studied in the photon-proton centre of mass energy range 165 GeV < W < 243 GeV and with Q < 0.01 GeV. Jets were defined using the longitudinally invariant kt algorithm. Events selected had o...
متن کاملRapidity Gaps Between Jets
An excess of events with a rapidity gap between jets, over what would be expected from non-diffractive processes, has been observed at HERA. A process based on a perturbative QCD calculation of colour singlet exchange has been added to HERWIG. With this addition, HERWIG is able to describe the number of events with a gap between jets over the number without a gap. This gap fraction is predicted...
متن کاملSuper-leading Logarithms in Gaps-between-jets
The resummation of large logarithms associated with wide angle soft gluon emissions has been investigated for the last 20 years. For certain observables the contributions from non-global logarithms 1 have to be taken into account. One of the simplest of these non-global observables is the ‘gaps-between-jets’ cross-section. This is the cross-section for producing a pair of high transverse moment...
متن کاملGaps between Jets: Matching two Approaches
We 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 ...
