Average minijet rapidity ratios in Mueller-Navelet jets

TL;DR

This paper examines the average rapidity ratios of minijet emissions in Mueller-Navelet jets at hadron colliders, incorporating transverse momenta and analyzing stability under quantum corrections and resummation.

Contribution

It introduces a modified observable combining rapidities and transverse momenta, and studies its stability with higher order corrections and transverse momentum vetoes.

Findings

Observable remains stable with higher order quantum corrections.

Inclusion of collinear resummation does not significantly alter results.

Transverse momentum veto influences minijet multiplicity but not the stability of the ratio.

Abstract

We investigate different final state features in Mueller-Navelet jets events at hadron colliders. The focus lies on the average rapidity ratio between subsequent minijet emissions which has been investigated in previous works but now is modified to also incorporate the transverse momenta together with the rapidities of the emitted jets. We study the dependence of this observable on a lower transverse momentum veto which does affect the typical minijet multiplicity of the events under scrutiny. We find that this observable is stable when including higher order quantum corrections, also when collinear terms are resummed to all orders.
