Synthesis of Research Findings on Dark Matter-Neutrino Interactions

Abstract

This study examines the synergistic interplay between dark matter and astrophysical neutrinos, with a focus on the utilization of neutrinos as indirect probes for dark matter characteristics. A holistic review is conducted of cosmological and multi-messenger datasets, incorporating key cosmological surveys, spectral line measurements, and high-energy neutrino observatory data. This integrated analysis enables the derivation of stringent constraints on dark matter-neutrino interactions from cosmological observations, the establishment of a 4.1 keV lower mass limit for sterile neutrinos based on spectral line measurements, and the confirmation of astrophysical neutrino origins via resonance event observations. The findings indicate that combined data robustly challenge specific theoretical aspects of the standard cosmological model and emphasize the critical role of neutrino observations in dark matter detection. The innovative integration of diverse observational evidence advances the refinement of dark matter parameters and proposes directions for future collaborative experiments, thereby underscoring significant cross-disciplinary implications in high-energy physics.
