A seesaw model for large neutrino masses in concordance with cosmology
Abstract Cosmological constraints on the sum of the neutrino masses can be relaxed if the number density of active neutrinos is reduced compared to the standard scenario, while at the same time keeping the effective number of neutrino species N eff ≈ 3 by introducing a new component of dark radiatio...
