TL;DR
This paper reports a search for Secluded Dark Matter in the Sun using ANTARES data, exploring various decay scenarios, and sets constraints on dark matter properties due to no observed excess.
Contribution
It introduces a novel search strategy for Secluded Dark Matter in the Sun with neutrino telescopes, considering multiple mediator decay channels.
Findings
No significant excess detected over background
Constraints established on dark matter mass
Limits set on mediator lifetime
Abstract
A search for Secluded Dark Matter annihilation in the Sun using 2007-2012 data of the ANTARES neutrino telescope is presented. Three different cases are considered: a) detection of dimuons that result from the decay of the mediator, or neutrino detection from: b) mediator that decays into a dimuon and, in turn, into neutrinos, and c) mediator that decays directly into neutrinos. As no significant excess over background is observed, constraints are derived on the dark matter mass and the lifetime of the mediator.
