Decays of Long-Lived Relics and Their Signatures at IceCube

Kim Berghaus, Johns Hopkins University

The 5.6 sigma high-energy neutrino excess at the IceCube detector could be an indicator of physics beyond the standard model. I will discuss the scenario of long-lived relics decays, with lifetimes shorter than the age of the universe, sourcing the neutrino excess . I will show the constraints on this possibility that arise from light element abundances, CMB anisotropies, and diffuse gamma-ray spectra. I will also discuss the importance of including electroweak corrections when exploring new physics far beyond the electroweak scale.
