1WF.00001: Direct Determination of Neutrino Mass with KATRIN Invited Speaker: The Karlsruhe Tritium Neutrino experiment (KATRIN) is a next generation tritium $\beta$ decay experiment capable of performing a high precision direct measurement of the absolute mass of the electron neutrino. The projected sensitivity of the experiment is $m(\nu_{e}) < 0.2$ eV (90\% C.L.) improving upon previous experiments by an order of magnitude. An overview of the experiment and its current status will be presented. Some of the technical challenges being addressed by the experiment will also be discussed. KATRIN is scheduled to begin collecting data in 2009. Support for this project in the United States is provided by the DOE under contract DE-FG-97ER41020. [Preview Abstract] |

1WF.00002: Cuoricino to CUORE: Neutrinoless Double Beta Decay Measurements with TeO$_2$ Bolometers Invited Speaker: An introduction and status report are presented on the neutrinoless double beta ($\beta\beta0\nu$) decay search efforts at Cuoricino, a bolometric experiment located at the National Laboratory of Gran Sasso (LNGS) in Italy. Cuoricino, currently the largest operating bolometer in the world, consists of a single tower of 62 TeO$_2$ crystals (41 kg), which serve as both the source and detector for the $\beta\beta0\nu$ decays. The proposed CUORE (Cryogenic Underground Observatory for Rare Events) experiment will also be discussed. Similar in concept to Cuoricino, CUORE will consist of 988 TeO$_2$ crystals in 19 Cuoricino-like towers having a total mass of 750 kg. Although having various anticipated but tractable technical challenges, CUORE will have the sensitivity to observe $\beta\beta0\nu$ for effective masses extending into the inverse hierarchy. This work is supported in part by the US Department of Energy. [Preview Abstract] |

1WF.00003: Neutrino mass and mixing constrained by double beta decay Invited Speaker: I will try to review the constraints imposed by neutrinoless double beta decay and direct mass measurement. [Preview Abstract] |

1WF.00004: Neutrino Properties Beyond the Standard Model Invited Speaker: Recent experimental developments significantly enhanced our knowledge of neutrino mass and mixings. In this talk our current understanding of the neutrino properties beyond the Standard Model, such as neutrino magnetic moment, will be reviewed. This work was supported in part by the U.S. National Science Foundation Grant No. PHY-0244384 at the University of Wisconsin, and in part by the University of Wisconsin Research Committee with funds granted by the Wisconsin Alumni Research Foundation.

1WF.00005: Lepton flavor violation and neutrino mass Invited Speaker: In order to explore the neutrino mass matrix, we need to examine the Majonara nature of neutrino. The Majorana nature is explored through the lepton number violating processes such as the neutrino-less double decay, the conversion of muon to positron, muon to anti-muon, etc. In these processes, the Majorana CP phases play an important role. The neutrino mass matrix is most likely to arise through the see-saw mechanism. To explore this, we need to examine the leptogenesis and the lepton flavor violation processes as well. By combining all possible experiments, the neutrino mass matrix is discussed. [Preview Abstract] |
