Abstract:

Neutrinos are among the most elusive particles that we know of, playing a key role in particle physics and cosmological theories. In these models, our Universe is believed to be permeated by a Cosmic Neutrino Background (CNB), consisting of neutrinos that decoupled from ordinary matter just a second after the Big Bang. Despite growing evidence for the CNB's existence, direct detection of these relic neutrinos remains one of the most difficult tasks to achieve in modern physics.  Additionally, the mass of these particles is still unknown. PTOLEMY stands as one of the most promising projects in addressing both these points. In this talk, I present new ideas to make direct CNB detection possible, and outline the strategy that PTOLEMY will use to measure the neutrino mass with unprecedented precision. Achieving these goals will not only enhance our understanding of neutrino physics, but also offer deeper insights into the early Universe and fundamental particle physics.
