Abstract

Early in 2002, the Kamioka Liquid Scintillator Anti-Neutrino Detector (KamLAND) began its search for the disappearance of electron anti-neutrinos produced from power reactors in Japan. By the end of the year, first results from KamLAND showed a significant deficit in the observed reactor neutrino flux. Recently, KamLAND released the results of an improved measurement which provided strong evidence for the distortion of the observed anti-neutrino energy spectrum. These results demonstrate that neutrino oscillation is the underlying mechanism for lepton flavour transformation observed in solar neutrinos. In this talk, results from KamLAND will be presented.

Alan Poon is a candidate for the SNOLAB Tier II CRC and will be available for individual meetings. Refreshments will be available after the talk.
