Signals of Inert Doublet Dark Matter in Neutrino Telescopes

TL;DR

This paper investigates how inert doublet dark matter particles can be captured by the Sun and Earth, leading to neutrino signals detectable by neutrino telescopes, thus providing a potential method to identify dark matter.

Contribution

It provides calculations of neutrino detection rates from inert doublet dark matter annihilations in the Sun and Earth, linking dark matter models to observable neutrino signals.

Findings

Neutrino signals from dark matter annihilations are potentially detectable.

The inert doublet model predicts specific neutrino fluxes from celestial bodies.

Detection prospects depend on dark matter properties and telescope sensitivities.

Abstract

One of the simplest extensions of the Standard Model that explains the observed abundance of dark matter is the inert doublet model. In this theory a discrete symmetry ensures that the neutral component of an additional electroweak doublet scalar is stable, and constitutes a dark matter candidate. As massive bodies such as the Sun and Earth move through the dark matter halo, dark matter particles can become gravitationally trapped in their cores. Annihilations of these particles result in neutrinos, which can potentially be observed with neutrino telescopes. We calculate the neutrino detection rate at these experiments from inert doublet dark matter annihilations in the cores of the Sun and the Earth.
