"Precision Measurement of Neutrino Oscillation Parameters with KamLAND"

Presented by Daniel Dwyer, Caltech

Thursday, November 29, 2007, 3:00 pm — Small Seminar Room, Bldg. 510

The KamLAND experiment measures the oscillation of anti-neutrinos produced by distant nuclear reactors. I will present new results which include an almost fourfold increase in the detector exposure and an analysis of the entire inverse beta decay spectrum above the reaction threshold. From spectral distortion we find decisive
evidence of neutrino oscillation. I will report a precise value for {\Delta}m^{12} and stringent constraints on \theta_{12}, the oscillation parameters relevant for both reactor and solar neutrinos. Combining the KamLAND and solar neutrino experiment results give the current best measure of neutrino oscillation parameters.
