Flavorful Interactions of AGN Neutrinos with Dark Matter Spike
Abstract
IceCube-Gen2 is going to make the dream of precise flavor ratio measurement for high energy cosmic neutrinos a reality. Motivated by this prospect, we build a model for the interaction of neutrinos with the dark matter and study the impact of the neutrino interaction with the dark matter spike around active galactic nuclei on the neutrino flavor ratio measurement. We show that, under certain circumstances, the flavor measurement by IceCube-Gen2 may discriminate between this model and the standard expectation, (νe⊕:νμ⊕:ντ⊕)≃ (1/3:1/3:1/3), as well as the prediction for a damped muon source. We discuss how we can derive information about the spike as well as about the characteristics of the dark matter particles composing it by combining the flavor ratio measurements with the results of the terrestrial experiments determining the neutrino mass ordering and a potential deviation from the standard model predictions in the measurements of the tau decay modes.

Motivated by this prospect, we build a model for the interaction of neutrinos with the dark matter and study the impact of the neutrino interaction with the dark matter spike around active galactic nuclei on the neutrino flavor ratio measurement. We show that, under certain circumstances, the flavor measurement by IceCube-Gen2 may discriminate between this model and the standard expectation, (ν_e^⊕:ν_μ^⊕:ν_τ^⊕)≃ (1/3:1/3:1/3), as well as the prediction for a damped muon source. We discuss how we can derive information about the spike as well as about the characteristics of the dark matter particles composing it by combining the flavor ratio measurements with the results of the terrestrial experiments determining the neutrino mass ordering and a potential deviation from the standard model predictions in the measurements of the tau decay modes.
