Asymptotically Safe Dark Matter

TL;DR

This paper proposes a new dark matter interaction model where the coupling strength becomes finite at high energies, leading to unique phenomenology that can be tested through collider and indirect detection experiments.

Contribution

It introduces the concept of asymptotically safe dark matter, a novel paradigm where interaction strength remains finite at high energies, affecting detection strategies.

Findings

Partial mitigation of low-energy direct detection constraints.

Distinct high-energy phenomenology of the model.

Potential for collider and indirect detection to probe the model.

Abstract

We introduce a new paradigm for dark matter (DM) interactions in which the interaction strength is asymptotically safe. In models of this type, the coupling strength is small at low energies but increases at higher energies, and asymptotically approaches a finite constant value. The resulting phenomenology of this "asymptotically safe DM" is quite distinct. One interesting effect of this is to partially offset the low-energy constraints from direct detection experiments without affecting thermal freeze-out processes which occur at higher energies. High-energy collider and indirect annihilation searches are the primary ways to constrain or discover asymptotically safe dark matter.
