14 May Alessandro Minotti, LAPP Reactor antineutrino anomaly and light sterile neutrino: first experimental results and perspectives.



From the discovery of the neutrino to the measure of the last of the mixing angles, nuclear reactors have proved indispensable in the study of these particles, of which much remains to be unveiled. Recent and past measurements using reactor neutrinos rely on the prediction of their spectrum, a non-trivial exercise involving ad-hoc methods and carefully-selected assumptions. A 6% discrepancy between predicted and measured fluxes at very short baselines, known as reactor antineutrino anomaly, arose in 2011, prompting a considerable scientific production as well as the birth of new experiments aiming to study neutrino oscillation at very short baseline. Such anomaly can be in fact explained invoking the existence of a new sterile neutrino at the eV mass scale participating in the oscillation, an enticing hypothesis that ties to other anomalies already observed in the neutrino sector.
Now some of these projects are releasing first results, gnawing pieces of the allowed phase space. Is it enough to rule out the light sterile neutrino, or is there still room for this or more exotic explanation?

28 May D. Jason Koskinen Fundamental Neutrino Physics with a Gigaton of Ice: the Past, the Present, and the Future of IceCube



With a cubic kilometer of instrumented ice, the IceCube detector at the South Pole covers a vast neutrino energy range (GeV-PeV) to study a truly bizarre particle. The DeepCore low energy extension of IceCube collects tens of thousands of atmospheric neutrinos each year to probe a wide array of neutrino oscillation physics (neutrino mass ordering, numu disappearance, nutau appearance, sterile neutrino searches, and other exotic phenomena).
I will discuss recent results from atmospheric measurements and the first tau neutrino appearance results. I will conclude by covering the potential for neutrino oscillations and atmospheric neutrino physics with the next generation low energy infill of IceCube. Time permitting, connections with multi-messenger astronomy will be discussed.
