Neutrinos as cosmic messengers

TL;DR

This paper reviews the current understanding of neutrino oscillations and explores their potential as cosmic messengers, discussing their role in cosmology, origins of neutrino masses, and possible laboratory signals.

Contribution

It provides a concise overview of neutrino properties, their cosmological significance, and discusses models explaining neutrino masses along with experimental prospects.

Findings

Neutrinos could explain baryon asymmetry and dark matter.

Seesaw and low-scale models offer different origins for neutrino masses.

Laboratory signals may help distinguish neutrino mass models.

Abstract

I briefly review the current status of neutrino oscillation parameters and discuss the role of neutrinos as cosmological probes, that could possibly induce the baryon asymmetry as well as the dark matter in the Universe. I comment on the origin of neutrino masses in seesaw-type and low-scale models and mention some of their laboratory signals.
