Neutrino Oscillation Experiments

Abstract

Accelerator- and reactor-based experiments operating at the first maximum for atmospheric oscillation have been an important driver in our understanding of neutrino properties in recent years. The current generation of reactor-based experiments have measured the mixing angle θ 13 with great precision, while accelerator-based experiments have taken significant exposures with both vμ and beams to study their disappearance into other flavors, primarily sensitive to the mixing angle θ 23, and electron neutrinos appearing via vμ → ve and oscillations which are sensitive to the ordering of the neutrino mass eigenvalues and the CP-violating phase δCP . Both reactor- and accelerator-based experiments have measured the mass-splitting to great precision.This presentation covers the latest developments in neutrino oscillation experiments in the context of the standard three flavor paradigm. Other presentations in the session provided a theoretical overview [1] and covered short baseline experiments exploring large neutrino mass splittings and other phenomenon driven by physics beyond the three flavor paradigm [2], solar neutrinos [3], geoneutrinos, and supernova neutrinos [4].
