Multi-messenger hunts for heavy WIMPs
Geoff Beck

TL;DR
This paper explores the potential of the KM3NeT neutrino detector to detect heavy leptophilic fermionic dark matter particles, linking collider physics, cosmology, and indirect detection methods, especially focusing on ultra-faint dwarf galaxies.
Contribution
It proposes a novel approach using neutrino detection to probe heavy leptophilic dark matter models associated with the Madala hypothesis.
Findings
KM3NeT can effectively search for heavy leptophilic fermionic dark matter.
Ultra-faint dwarf galaxies like Triangulum II are promising targets.
Neutrino detection offers an alternative to gamma-ray methods for such dark matter searches.
Abstract
Heavy neutrinos have a long history of consideration in the literature, in particular related to their role as solutions to the problems of neutrino mass, baryon asymmetry, and possibly dark matter. Interestingly, recent developments in the Madala hypothesis, a standard model extension designed to explain persistent LHC lepton anomalies, may also necessitate a heavy neutrino. This prospect is exciting as a dark matter model consisting of a TeV-scale leptophilic fermionic particle is also invoked to explain the electron-positron excess observed by the DAMPE experiment. The tantalising similarities between these new fermions may allow indirect dark matter detection methods to probe empirically compelling standard model extensions, like the Madala hypothesis. However, the leptophilic nature and large mass mean the expected gamma-ray signatures of annihilation or decay are weaker than those…
