The New World of Neutrino Physics – Part II · Four Lectures
Stephen Parke (Fermilab)
February 21 – March 2, 2006

Thanks to many beautiful experiments during the last decade, we now know that neutrinos can change flavor and have nonzero masses, and that leptons mix. These discoveries raise interesting questions about the neutrinos and their connections to the rest of physics and astrophysics. In these lectures we will explain the physics of neutrino mass, Dirac and Majorana neutrinos, leptonic mixing, and neutrino flavor change in vacuo and in matter. We will review what has been learned so far, and discuss some of the most interesting open questions: Do neutrinos violate CP, and if they do, is this violation connected to the matter-antimatter asymmetry of the universe? Does the neutrino mass spectrum resemble the quark and charged-lepton spectra, as grand unification would suggest, or is it an upside-down version of those other spectra? Are neutrinos their own antiparticles? We will describe the ideas for answering these and other questions through future experiments.
