The high-energy radiation pattern from BFKLex

Abstract

We discuss a recent study on high-energy jet production in the multi-Regge limit done with the use of the Monte Carlo event generator BFKLex which includes collinear improvements in the form of double-log contributions. We will show results for the average transverse momentum and azimuthal angle of the final state jets when at least one of them is very forward in rapidity and another one is very backward. We also discuss the introduction of a new observable which accounts for the average rapidity ratio among subsequent emissions.

Causality and unitarity via the tree-loop duality relation

“…[20] and extensive references therein) have been very effective in the computation of one-loop and some two-loop amplitudes, and are being actively pursued in QCD (multi-leg) two-and higher loop implementations. In addition, the TLD relation itself has been directly used for evaluation of loop diagrams [6], [7]. The BCC representation provides a ready-made representation which, furthermore, can be used iteratively, as it can be applied to the lower-order cut graphs themselves.…”

“…[4], [5]. In [6], [7] numerical implementation of LTD was introduced and applied in the evaluation of multi-leg amplitudes.…”

“…In addition to multiplicity, other observables were recently proposed [21,22] using this mini-jet radiation…”
