Neutrino Masses and Dark Forces

Explore the fundamental physics of neutrino masses and their connection to dark forces in this comprehensive lecture delivered at the Galileo Galilei Institute. Delve into the theoretical frameworks that explain how neutrinos acquire mass, examining the mechanisms that govern these elusive particles and their interactions with hypothetical dark sector forces. Learn about the current understanding of neutrino physics, including the role of mass generation in the Standard Model and beyond, while investigating how dark forces might influence neutrino behavior and properties. Discover the experimental evidence supporting neutrino mass measurements and the theoretical implications for particle physics, cosmology, and our understanding of the universe's fundamental structure. Examine the mathematical formulations and physical principles underlying neutrino mass models, including seesaw mechanisms and their variants, as well as the potential connections between neutrino physics and dark matter interactions. Gain insights into cutting-edge research methodologies used to study these phenomena and understand how neutrino mass studies contribute to our broader knowledge of physics beyond the Standard Model.
