“…all terms ∼ α n s ln n (s/|t|), are summed up using the formalism of BFKL [13]. Calculations have been performed for all of the above processes to leading logarithmic accuracy, see [14] for a recent summary.…”

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 exchange we find agreement provided that a constant value of α s is used in the BFKL calculation. Moreover, the value of α s is in line with that extracted from measurements made at HERA.

“…The two best developed models currently available are the BFKL pomeron [ 6], calculated within the leading logarithmic approximation (LLA) by Mueller and Tang [ 7] and implemented into the HERWIG Monte Carlo [ 8,9], and the soft colour rearrangement model [ 10]. The recent gaps between jets analysis by the D0 Collaboration [ 1] favoured the soft colour model to the BFKL pomeron, although conclusions from gaps between jets measurements may be difficult to draw due to the uncertainties in the role of multiple interactions, which are poorly understood theoretically at the present time [ 11,12]. Furthermore, gaps between jets measurements at both HERA and the TEVA-TRON are limited by the requirement that two jets are observed in the detector, severely restricting the accessible gap size.…”
