- Abstract
Early Universe cosmology imposes stringent bounds on light sterile neutrinos mixing with the active flavors. Here we discuss how altered dispersion relations can weaken such bounds and allow compatibility of new sterile neutrino degrees of freedom with early Universe cosmology and particular a successful generation of the light elements in the early Universe.
