B2.00001: W. K. H. Panofsky Prize: The Road to Neutrino Mixing Angle $\theta_{13}$ Invited Speaker: Kam-Biu Luk A series of solar, atmospheric, accelerator and reactor neutrino experiments have observed transformations of one type of neutrino to another type. This intriguing phenomenon called neutrino oscillation was predicted by Pontecorvo, Maki, Nakagawa and Sakata. It is due to the fact that the three flavors of neutrinos observed in laboratories are mixtures of three neutrino mass eigenstates. Neutrino mixing is described by a set of three mixing angles and a CP-violating phase. The smallest angle, $\theta_{13}$, was unknown until 2012. Knowing the value of $\theta_{13}$ is essential. Besides being a fundamental parameter of nature, knowing its value will improve our understanding of neutrino mixing, provide guidance for building theoretical models and define the future program of neutrino oscillation experiments. In this talk, the experimental development that led to the recent discovery of a new $\theta_{13}$-driven neutrino oscillation will be presented. [Preview Abstract] |

B2.00003: Henry Primakoff Award: The Mixed-Up Neutrino: Precision Measurement of Oscillation at Daya Bay Invited Speaker: Daniel Dwyer It is estimated that there are more neutrinos in the universe than all of the atoms in the stars, the planets, and us. Yet until recently this particle was poorly understood. Neutrinos are nearly decoupled from the universe we know, tied only by the rare weak interaction. The Daya Bay Experiment in Southern China provided an ideal location to characterize these elusive particles. Six identical detectors measured the relative flux versus distance of electron antineutrinos emitted by nuclear reactors. The disappearance of electron antineutrinos revealed an unexpectedly large mixing of neutrino flavor, and also provided an independent estimate of the larger neutrino mass difference. I will present the details of this measurement, including expected and unexpected obstacles faced along the way. I will then discuss the implications of our observations and future steps in neutrino physics. [Preview Abstract] |
