Dr Antonio Palazzo (IFIC, CSIC/University of Valencia)13/03/2009 17:00Pinning down the unknown neutrino mixing angle theta_13 is one of the most important goals in particle physics in connection with future investigation on CP violation in the leptonic sector. In this context, I shall present the results of an updated global analysis of neutrino oscillation data, focusing on this puzzling parameter. I shall discuss two independent and converging hints of...Go to contribution page

Dr Makoto Miura (Kamioka observatory, ICRR, University of Tokyo)13/03/2009 17:20The standard model has been successful in accounting for many experimental results. However, the standard model has unanswered questions: why there are so many parameters? Various attempts have been made to resolve the shortcomings by unifying the electroweak and the strong interactions in the context of Grand Unified Theory (GUT). One of the generic predictions of GUTs is the instability of...Go to contribution page

Philip Rubin (George Mason University)13/03/2009 17:40By determining the disappearance rate of anti-neutrinos emitted from the Daya Bay and Ling Ao nuclear power plants in Southeast China, the Daya Bay Reactor Neutrino Experiment will achieve a 1% sensitivity to sin(2*theta_13). The current best limit, by Chooz, is 17%. Beginning three years of data taking in 2011, Daya Bay will be the most precise of the new generation of experiments intended...Go to contribution page

Dr Amanda Porta (CEA Saclay)13/03/2009 17:55Double Chooz main target is to measure the Theta13 oscillation parameter by comparing the reactor neutrino fluxes in two identical detectors located respectively at 400 m and 1 km away from the 2 Chooz reactor cores. The detector target consists of 10 m3 of Gd-doped liquid scintillator surrounded by a 55 cm-thick g-catcher of non-loaded liquid scintillator. This central part is observed by...Go to contribution page

Mme Chiara Arina (Universite Libre de Bruxelles)13/03/2009 18:10We study the minimal SUGRA phenomenology in the case of an alternative seesaw mechanism for generating neutrino masses. Changes in the neutrino sector lead to a modification of the supersymmetric particle spectrum and the sneutrino naturally arises as the lightest supersymmetric particle. The obtained sneutrino has a relic density within the WMAP range and is compatible with present...Go to contribution page

Mme Irene Tamborra (Department of Physics, University of Bari & INFN, Bari)13/03/2009 18:45When the neutrino density is very high, as in core-collapse supernovae, neutrino-neutrino interactions are not negligible and can appreciably influence the evolution of flavor. The physics of these phenomena is briefly highlighted, and their effects are shown on observable energy spectra from a future galactic supernova. Detection of such effects could provide a handle on two unknowns: the...Go to contribution page

Lindley Winslow (Massachusetts Institute of Technology)13/03/2009 19:05KamLAND is a one-kiloton liquid scintillating detector located in the Kamioka Mine in Kamioka, Japan. KamLAND measurements have shown evidence for neutrino oscillation in reactor anti-neutrinos and indications of geological produced anti-neutrinos. The first phase of KamLAND acquired almost 1500 days of data. An analysis of this full data set with improvements in calibration and the...Go to contribution page

Dr Marco Picariello (Università del salento)13/03/2009 19:25We investigate the resonant spin flavour conversion of solar neutrinos to sterile ones, a mechanism which is added to the well known LMA one. We show that the data from all solar neutrino experiments except Borexino exhibit a clear preference for a sizable magnetic field. We argue that the solar neutrino experiments are capable of tracing the possible modulation of the solar magnetic field....Go to contribution page

M. Timo Lewke (Borexino/ Technische Universität München)13/03/2009 19:45Borexino is a low threshold liquid-scintillator detector for solar neutrinos located in the LNGS underground laboratory, Italy. Because of the ultra-high radio purity it is the first experiment able to do a real time analysis of the low energetic solar neutrinos. A detection of the solar ⁷Be neutrinos with a rate of 47+-7 counts/day/100tons was reported (192 days of live time measurement). ⁸B...Go to contribution page
