"Recent Results and Future Prospects in Neutrino Physics"
ABSTRACT:
More than 40 years ago, a Nobel Prize winning experiment showed that neutrinos come in distinct flavors: neutrinos created in association with muons produced only muons when they interacted, and not electrons. Over the past decade, however, a series of experiments have established that the flavor of a neutrino does indeed change with time. The most likely explanation of this phenomenon is neutrino flavor oscillation, requiring a finite neutrino mass and therefore an extension of the Standard Model of Particle Physics. Related physics at energies far beyond direct experimental reach may well explain the preponderance of matter over antimatter in the universe. The impact of accelerator-based experiments in our understanding of neutrino masses and flavor will be discussed, with an emphasis on current and anticipated experiments at Fermilab.
