TL;DR

This paper investigates how LHC measurements can constrain composite dark matter models with SU(N) gauge groups, linking collider data to dark matter properties and exploring future detection prospects.

Contribution

It introduces a novel analysis connecting LHC differential cross-section data to constraints on stealth dark matter models with SU(N) gauge groups, incorporating lattice results.

Findings

LHC measurements constrain dark matter masses around 10 TeV.

Current data limits the parameter space of composite dark matter models.

Potential future LHC strategies could further explore these models.

Abstract

We present sensitivity of LHC differential cross-section measurements to so-called "stealth dark matter" scenarios occurring in an SU(N) dark gauge group, where constituents are charged under the Standard Model and N=2 or 4. The low-energy theory contains mesons which can be produced at the LHC, and a scalar baryon dark matter (DM) candidate which cannot. We evaluate the impact of LHC measurements on the dark meson masses. Using existing lattice results, we then connect the LHC explorations to DM phenomenology, in particular considering direct-detection experiments. We show that current LHC measurements constrain DM masses in the region of 10 TeV. We discuss potential pathways to explore these models further at the LHC.
