Hard Colour Singlet Exchange at the Tevatron from the Bfkl Equation
نویسنده
چکیده
We study rapidity gaps between jets in pp̄ collisions at the Tevatron by a novel solution of the nonforward BFKL equation including nonleading effects through the consistency constraint and running coupling. Results differ from earlier calculations based on the asymptotic Mueller-Tang formula, but agree with D0 data when including full event simulation using PYTHIA to model the gap survival probability.

Hard colour singlet exchange and gaps between jets at the Tevatron
The new kind of events with a rapidity gap between two high-ET jets, observed in high energy pp̄ collisions at the Tevatron, is found to be well described by the exchange of a colour singlet gluon system in the BFKL framework. This requires going beyond the conventional asymptotic Mueller–Tang approximation, which results in qualitatively different features of the basic parton–parton scattering ...
متن کاملHard Colour Singlet Exchange at the Tevatron
We have performed a detailed phenomenological investigation of the hard colour singlet exchange process which is observed at the Tevatron in events which have a large rapidity gap between outgoing jets. We include the effects of multiple interactions to obtain a prediction for the gap survival factor. Comparing the data on the fraction of gap events with the prediction from BFKL pomeron exchang...

متن کاملDiffractive vector mesons at large momentum transfer from the BFKL equation ∗
Diffractive vector meson photoproduction accompanied by proton dis-sociation is studied for large momentum transfer. The process is described by the non-forward BFKL equation, for which an analytical solution is found for all conformal spins, giving the scattering amplitude. Results are compared to HERA data on ρ production. Diffractive production of vector mesons in γp collisions at large mome...
