abstract

The recent observation of the ultrahigh-energy neutrino event KM3-230213A by the KM3NeT experiment offers a compelling avenue to explore physics beyond the Standard Model (SM). In this paper, we explore a simplest possibility that this event originates from the decay of a super-heavy dark matter (SHDM). We consider a minimal scenario where the SHDM decays to neutrino and SM Higgs. We derive constraints on the DM lifetime as a function of DM mass, ensuring consistency with IceCube, Auger upper limits, and the observed KM3-230213A event, along with the gamma-ray constraints. We find that KM3-230213A gives stringent constraint on the DM mass ranging from $1.5\times10^8$ GeV to $5.2\times10^9$ GeV with lifetime in the range: $1.42\times10^{30}$ s to $5.4\times10^{29}$ s. Remarkably, in our SHDM scenario, the apparent tension between the KM3NeT observation and the nonobservation of this event by IceCube and Auger can be reduced to below $1.2\sigma$. Our results are applicable to any neutrinophilic SHDM models while evading gamma-ray constraints.

    hep-ph 2025-09 conditional novelty 5.0

    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.

    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...
