Neutrino masses and mixings dynamically generated by a light dark sector

E Bertuzzo, S Jana, PAN Machado, RZ Funchal - Physics Letters B, 2019 - Elsevier
Neutrinos may be the harbingers of new dark sectors, since the renormalizable neutrino
portal allows for their interactions with hidden new physics. We propose here to use this fact …
