Seminario M. Gerbino

Per il ciclo "Physics Colloquia" il giorno 12 dicembre alle ore 16 presso l'aula 412, Martina Gerbino (Istituto Nazionale di Fisica Nucleare) terra' un seminario dal titolo

The left hand of lightness: how we get to understand neutrinos (and other particles) by hunting for the most ancient light in the Universe

Abstract
Neutrinos are copiously produced in the early stages of the Universe history. They are the second most abundant species after cosmic photons to been wandering through the cosmic web for billions of years. They are also the most puzzling particles within the standard model of particle physics. Many of their properties - and the physical origin of these properties - are still mysterious. We have never measured their total mass (but we know for sure they have mass), we cannot explain where it comes from, we do not know whether neutrinos are their own antiparticles. However, we do know that neutrinos played - and still play - an important role in shaping the Universe as we observe it today.
In this colloquium, we will discover how the observation of the cosmic microwave background (CMB) - the relic radiation from the Big Bang - can unveil the mysteries of neutrinos. On top of this, throughout its long history, the Universe may have seen the birth of new relic particles still to be discovered, or even the manifestation of exotic properties of known particles still to be detected. We will learn how cosmology promises to open the window to the beyond-the-standard-model landscape that physicists have been longing for.
