Neutrino Interferometry with DUNE

Deborah Harris
York University
Senior Scientist, Fermilab

Abstract

Neutrinos are fascinating particles because they were created less than a second after the Big Bang and hence are one of the few particles to provide a window into the creation of the universe.  There are now a billion times more neutrinos than the particles that make up normal matter, yet we know little about neutrinos because they rarely interact.  We know neutrinos come in three different kinds, and they transform (or oscillate) from one kind to another (a discovery that received the 2015 Physics Nobel Prize).  The fact that neutrinos have mass and oscillate means that we can learn a great deal about them by studying what are effectively interference patterns that arise after neutrinos propagate over hundreds of kilometers.  The DUNE experiment will measure these interference patterns over a broad neutrino energy range after neutrinos have propagated 1300km.  In addition, DUNE will use a detector technology that provides exquisite detail about the interactions that make up the interference pattern.  This talk will present the current status of oscillation measurements and of recent progress on preparations for DUNE.
