Neutrino Oscillation Experiments

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 theta(13) with great precision, while accelerator-based experiments have taken significant exposures with both nu(mu), and (nu) over bar (mu) beams to study their disappearance into other flavors, primarily sensitive to the mixing angle theta(23), and electron neutrinos appearing via nu(mu) -> nu(e) and (nu) over bar (mu) -> (nu) over bar (e) oscillations which are sensitive to the ordering of the neutrino mass eigenvalues and the CP-violating phase delta(CP). Both reactor- and accelerator-based experiments have measured the mass-splitting Delta m(atm)(2), 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].
