Description

What if the dark matter content of the universe was made up of sterile neutrinos with a mass of the order of keV?
Currently, constraints from the measured relic abundance of dark matter and from observations in the X-ray band threaten the possibility of finding in terrestrial experiments a signal of such sterile neutrinos produced through oscillation and collisions in the early universe.
We look at two scenarios in which the simple hypothesis of

  • a low reheating temperature
  • a new contribution to the sterile neutrino decay process

naturally relax these constraints and give new vigor to the hope of getting in the near future a proof of the existence of these elusive Dark Matter candidates in experiments such as KATRIN and ECHo.
