What KM3-230213A events may tell us about the neutrino mass and dark matter
abstract
Within the framework of general $U(1)$ scenario, we demonstrate that the ultra high energy neutrinos recently detected by KM3NeT could originate from a decaying right handed neutrino dark matter (DM), with a mass of 440 PeV. Considering DM production via freeze-in, we delineate the parameter space that satisfies the observed relic abundance and also lies within the reach of multiple gravitational wave detectors. Our study provides a testable new physics scenario, enabled by multi-messenger astronomy.

Earth rotation turns event timing into a geometric probe of UHE neutrino origin
Earth-rotation timing lowers the number of future KM3NeT events needed to exclude a dark-matter origin of KM3-230213A from ~22–27 to ~14–16.

Constraining Gravitational Dark Matter with LHAASO and Fermi-LAT
Diffuse Galactic gamma-ray data strongly limit the couplings of gravitationally produced decaying dark matter, and the paper claims an oscillation-based bound on massive dark photons.

Breaking Dark: Hunting Heavy Decaying Dark Matter with Tibet AS$_\gamma$ and LHAASO-KM2A
Tibet ASγ and LHAASO-KM2A diffuse gamma-ray data exclude decaying dark matter lifetimes below about 10^28 seconds for masses around 10^6-10^9 GeV, for many Standard Model final states.

Testing Heavy Dark Matter Decay as the Origin of KM3-230213A
Assuming the KM3-230213A event comes from heavy dark matter decay, the preferred mass exceeds 100 PeV at 95% CL with lifetimes of 10^26-10^27 s, but these regions conflict with bounds from other neutrino telescopes an...
