Neutrino Masses and Lepton-Quark Symmetries
P. Ramond (Physics Department, University of Florida)🇺🇸
Abstract
The recent discovery by SuperKamiokande of evidence for neutrino masses requires the addition of at least seven new parameters to the Standard Model. We discuss the general theoretical schemes which require their inclusion, and point out how quark-lepton symmetries, either in the framework of Grand Unification, or of string theories, can be used to determine them
