Dark Matter-Neutrino Interaction in Light of Collider and Neutrino Telescope Data

TL;DR

This paper investigates dark matter-neutrino interactions using simplified models, analyzing bounds from collider experiments and neutrino telescopes, and finds that the effectiveness of these bounds depends on the dark matter type and mediator mass.

Contribution

It provides a comparative analysis of collider and neutrino telescope bounds on dark matter-neutrino interactions within simplified models, including different dark matter types and mediator masses.

Findings

LHC bounds are stronger for scalar dark matter.

Neutrino telescopes provide more stringent bounds for fermionic dark matter above 200 MeV.

Bounds vary with mediator mass and dark matter type.

Abstract

We study the DM-neutrino interaction in the framework of simplified model. The phenomenology of such an interaction are derived. We also investigate the bound on DM-neutrino interaction from the LHC and neutrino telescopes. We find that for the case of a scalar dark matter, the LHC gives a stronger bound on dark matter annihilation cross-section than the neutrino telescopes. However, for the fermionic dark matter case the neutrino telescopes bounds are more stringent for dark matter mass, $\gtrsim 200$ MeV. In the case of lower DM mass, the neutrino telescopes provide better bounds for a light mediator, while the collider bounds are better for a heavy mediator. Possible UV completions of the simplified model are briefly discussed.
