Complementarity of Dark Matter Searches at Resonance

TL;DR

This paper investigates the potential to detect or exclude certain dark matter models at resonance, where traditional direct detection methods are ineffective, using future collider and astrophysical observations.

Contribution

It introduces a simple vector boson-mediated dark matter model and assesses the prospects of future collider and gamma-ray observations to probe resonance regions.

Findings

Future LHC dijet measurements can constrain resonance dark matter models.

CTA and AMS observations of the Galactic Centre can provide complementary exclusion limits.

Resonance regions may remain challenging to exclude with current detection methods.

Abstract

We consider models of dark matter where the couplings between the standard model and the dark sector fall at resonance due to kinematics and direct detection experiments become insensitive. To be specific, we consider a simple model of 100 GeV - TeV scale dark matter coupled to the standard model via a vector boson. We explore whether it will be possible to exclude such regions of the parameter space using future observations of dijet rates at the LHC and CTA and AMS observations of the Galactic Centre.
