# Constraining Secluded Dark Matter models with the public data from the 79-string IceCube search for dark matter in the Sun

## TL;DR

This paper uses IceCube data to set new constraints on Secluded Dark Matter and dark photon models, demonstrating neutrino telescopes' potential in probing dark sector physics.

## Contribution

First constraints on dark photons from neutrino telescopes, and application of IceCube data to test Secluded Dark Matter models.

## Key findings

- No significant dark matter signal observed in IceCube data.
- Constraints established on dark photon parameters in the 0.22-1 GeV mass range.
- Neutrino telescopes can effectively test dark photon models.

## Abstract

The 79-string IceCube search for dark matter in the Sun public data is used to test Secluded Dark Matter models. No significant excess over background is observed and constraints on the parameters of the models are derived. Moreover, the search is also used to constrain the dark photon model in the region of the parameter space with dark photon masses between 0.22 and $\sim$ 1 GeV and a kinetic mixing parameter $\varepsilon \sim 10^{-9}$, which remains unconstrained. These are the first constraints of dark photons from neutrino telescopes. It is expected that neutrino telescopes will be efficient tools to test dark photons by means of different searches in the Sun, Earth and Galactic Center, which could complement constraints from direct detection, accelerators, astrophysics and indirect detection with other messengers, such as gamma rays or antiparticles.
