A Simplified Model for Dark Matter Interacting Primarily with Gluons

TL;DR

This paper introduces a simplified, renormalizable model where scalar dark matter interacts mainly with gluons through scalar colored mediators, affecting annihilation, scattering, and collider signals.

Contribution

It presents a novel dark matter model with colored scalars that decay into multi-quark states, differing from typical models with missing energy signatures.

Findings

Dark matter annihilation and scattering are influenced by gluon interactions.

Colored scalars decay into multi-quark final states without missing energy.

The model's collider signatures differ from conventional dark matter models.

Abstract

We consider a simple renormalizable model providing a UV completion for dark matter whose interactions with the Standard Model are primarily via the gluons. The model consists of scalar dark matter interacting with scalar colored mediator particles. A novel feature is the fact that (in contrast to more typical models containing dark matter whose interactions are mediated via colored scalars) the colored scalars typically decay into multi-quark final states, with no associated missing energy. We construct this class of models and examine associated phenomena related to dark matter annihilation, scattering with nuclei, and production at colliders.
