abstract

We constrain the neutrino-dark matter cross-section using the $13 \pm 5$ neutrino event excess observed by IceCube in 2014-2015 from the direction of the blazar TXS 0506+056. Our analysis takes advantage of the dark matter overdensity spike surrounding the supermassive black hole at the center of the blazar. In our results, we take into account uncertainties related to the different types of neutrino emission models and the features of the dark matter spike, considering cross-sections that scale with energy as $\sigma \propto (E_{\nu} /E_0)^n$, for values of $n = 1, 0, -1, -2$. In our best-case scenario, we obtain limits competitive with those derived from other active galaxies, tidal disruption events (TDEs), and the IC-170922A event.

  1. Astrophysical Neutrino Sources as Colliders

    hep-ph 2026-07 conditional novelty 7.0 of 10

    Neutrino point-source observations (IceCube, KM3NeT) can bound inelastic pp and pγ cross sections from √s ≈ 1 GeV to ~10^5 GeV, extending beyond LHC/HERA and sometimes below unitarity limits.

  2. Flavorful Interactions of AGN Neutrinos with Dark Matter Spike

    hep-ph 2026-07 conditional novelty 6.5 of 10

    IceCube-Gen2 flavor ratios can discriminate a U(1) neutrino–dark-matter model in AGN spikes from the standard (1/3:1/3:1/3) and muon-damped predictions, and, combined with mass-ordering and tau-decay data, constrain t...

  3. Dark Matter Heating of Compact Stars Beyond Capture: A Relativistic Framework for Energy Deposition by Particle Beams

    hep-ph 2026-02 conditional novelty 6.0 of 10

    A new relativistic formalism computes capture and energy deposition of directed particle beams in compact stars, applied to blazar-boosted dark matter heating of white dwarfs and neutron stars.

  4. The Highest-Energy Neutrino Event Constrains Dark Matter-Neutrino Interactions

    hep-ph 2025-06 conditional novelty 6.0 of 10

    KM3-230213A limits dark matter-neutrino scattering to below about 1e-22 cm^2/GeV at 220 PeV, but most simple dark matter models are excluded by unitarity above MeV masses.
