Sterile neutrino dark matter from generalized -symmetric early-Universe cosmologies
Abstract
We generalize gravitational particle production in a radiation-dominated CPT-symmetric universe to nonstandard but also CPT-symmetric early-Universe cosmologies. We calculate the mass of a right-handed “sterile” neutrino needed for it to be the cosmological dark matter. Since generically sterile neutrinos mix with the standard model active neutrinos, we use state-of-the-art tools to compute the expected spectrum of gamma rays and high-energy active neutrinos from ultraheavy sterile neutrino dark matter decay. We demonstrate that the sterile neutrinos are never in thermal equilibrium in the early Universe. We show that very high-energy Cherenkov telescopes might detect a signal for sterile neutrino lifetimes up to around 1027 s, while a signal in high-energy neutrino telescopes such as IceCube could be detectable for lifetimes up to 1030 s, offering a better chance of detection across a vast landscape of possible masses.
