CA.00001: Searching for Neutrino Oscillations with MiniBooNE Invited Speaker: Here we present the first results of a serach for $\nu_e$ appearance in a $\nu_\mu$ beam. Two independent analyses observe no significant excess of events above the calculated background for reconstructed neutrino energies above 475 MeV. The data are consistent with no oscillations within a two-neutrino, appearance-only neutrino model. [Preview Abstract] |

CA.00002: $\nu$-SNS, A Neutrino Program at the Spallation Neutron Source Invited Speaker: During the past few years, outstanding progress has been made in our understanding of the neutrino properties. Recent results from neutrino experiments have conclusively shown that neutrinos undergo oscillations, that is they can change from one type of neutrino to another, and the fact that neutrinos do oscillate is indicative of the various neutrino species having non zero mass. However, there still remain many open questions regarding the role that neutrinos play in the various physical processes that occur in the Universe. One of these open questions is the role that neutrinos play in Supernova explosions. Neutrinos can carry away up to 99{\%} of the total energy that is released during the core collapse. They thus affect the both the dynamics of the supernova explosion and the nucleosynthesis. To understand the role that neutrinos play during the supernova explosion, it is necessary to have precise knowledge of neutrino interactions with the nuclei at the low energy. The $\nu$-SNS program at ORNL is directed toward accurately measuring the neutrino-nucleus cross section at supernovae neutrino energies for a wide range of nuclei. [Preview Abstract] |

CA.00003: Accelerator Neutrinos Invited Speaker: After a brief review of the current neutrino oscillation status, we present neutrino oscillation results for recent and current accelerator-based neutrino experiments including K2K, MiniBooNE and MINOS experiments. We also foreshadow to prospects and status of future various accelerator-based neutrino physics programs around the world. A by-product of the vibrant oscillation program is a program of neutrino scattering scattering experiments. We will summarize the status of these experiments including SciBOONE and MINERvA experiments. [Preview Abstract] |

CA.00004: Neutrinoless Double Beta Decay Invited Speaker: Neutrinoless double beta decay is a hypothetical process where an atomic nucleus decays with the emission of two electrons and no neutrinos. The observation of this process would have significant physical implications. It would imply that absolute lepton number is violated and that neutrinos are Majorana particles. It can also provide a measurement of the absolute mass scale of the neutrino. This talk will review the theory of neutrinoless double beta decay, as well as previous, current and future experimnetal efforts to detect this extremely rare process. [Preview Abstract] |
