Sterile neutrinos, dark matter, and resonant effects in ultra high energy regimes

Understand

Interest in light dark matter candidates has recently increased in the literature; some of these works consider the role of additional neutrinos, either active or sterile.

• Furthermore, extragalactic neutrinos have been detected with energies higher than have ever been reported before.
• This opens a new window of opportunities to the study of neutrino properties that were unreachable up to now.
• We investigate how an interaction potential between neutrinos and dark matter might induce a resonant enhancement in the oscillation probability, an effect that may be tested with future neutrino data.
