Resonant Lepton-Gluon Collisions at the Large Hadron Collider

TL;DR

This paper explores resonant lepton-gluon collisions at the LHC to enhance searches for leptogluons, demonstrating potential to extend mass reach and distinguish leptogluons from similar particles.

Contribution

It introduces a novel resonant production mechanism for leptogluons using lepton parton densities, extending search capabilities beyond previous methods.

Findings

Leptogluons up to ~3.5 TeV can be probed.

Discrimination between leptogluons and leptoquarks is feasible.

Combining channels improves exclusion limits.

Abstract

We study the lepton-induced resonant production of color-adjoint leptons (leptogluons) at the LHC employing the lepton parton density function of the proton. We demonstrate that this production mechanism can be useful to extend the LHC ability to search for leptogluons beyond purely quark/gluon initiated production processes up to ~ 3.5 TeV leptogluon masses and O(1) TeV compositeness scales. Discerning leptogluons from scalar and vector leptoquarks is also possible in this channel, given a data sample containing the order of 100 signal events. We argue that the resonant channel can be combined with leptogluon pair and associated leptogluon-lepton productions to boost exclusion limits and discovery prospects at the LHC.
