Olivier Mattelaer, Eleni Vryonidou
TL;DR
This paper presents a method to simulate dark matter production via loop-induced processes at the LHC, focusing on s-channel mediators and gluon-initiated interactions, within the MadGraph5_aMC@NLO framework.
Contribution
It introduces a new implementation for studying mono-X signatures involving loop-induced processes with s-channel mediators in a widely used simulation tool.
Findings
Enables simulation of missing energy plus jets or neutral bosons at the LHC.
Incorporates effects of extra radiation through multi-parton merging.
Focuses on mediators coupling to third generation quarks, especially top quarks.
Abstract
We show how studies relevant for mono-X searches at the LHC in simplified models featuring a dark matter candidate and an -channel mediator can be performed within the MadGraph5_aMC@NLO framework. We focus on gluon-initiated loop-induced processes, mostly relevant to the case where the mediator couples preferentially to third generation quarks and in particular to the top quark. Our implementation allows us to study signatures at hadron colliders involving missing transverse energy plus jets or plus neutral bosons (), possibly including the effects of extra radiation by multi-parton merging and matching to the parton shower.
