A background radiation of relic neutrinos, originated during the early phases of the Universe expansion, is predicted by the standard cosmological model, but has never been confirmed by a direct measurement. Indirect probes already provide information on relic neutrinos, but future direct detection experiments will give us many more details to understand the properties of these extremely elusive particles. In this seminar, I will review some of the aspects related to the theoretical study of relic neutrinos properties including standard and non-standard physics: I will talk about their momentum distribution function, local number density, and the effect of additional neutrino states. Finally, I will discuss what future direct detection experiments, such as PTOLEMY , can teach us.
