Towards detecting super-GeV dark matter via annihilation to neutrinos

Abstract The next generation of neutrino telescopes will feature unprecedented sensitivities in the detection neutrinos. Here we study capabilities a large-scale telescope, like fully-operating KM3NeT experiment near future, for detecting dark matter annihilation signals from Galactic Centre. We consider both ORCA and ARCA detectors, covering masses few GeV to 100 TeV. obtain with maximum-likelihood analysis method present them as upper limits thermally averaged cross-section into Standard Model fermions. Our projections show that sensitivity such telescope can reach thermal relic line m χ ≳ 1 TeV ≃ GeV, NFW density profile. This demonstrates ORCA- ARCA-like detectors be able perform competitive searches wide range masses. implications these striking are investigated selected particle models, where probe new parameter space.
