Speaker: Luca Vecchi (EPFL) I discuss scenarios in which a dark light sector couples to the Standard Model via the so-called “neutrino portal”. A generic implication of this framework is the existence of gauge-singlet fermions (sterile neutrinos) that act as messengers between the dark sector and the active neutrinos. I show under which conditions cosmological constraints become inefficient and discuss what new phenomena neutrino oscillation​ experiments may be able to observe.
