Kamland Results
Abstract
The LMA solution of the solar neutrino problem has been explored with the 1,000 ton liquid scintillator detector, KamLAND. It utilizes nuclear power reactors distributing effectively ~180 km from the experimental site. Comparing observed neutrino rate with the calculation of reactor operation histories, an evidence for reactor neutrino disappearance has been obtained from 162 ton · year exposure data. This deficit is only compatible with the LMA solution and the other solutions in the two neutrino oscillation hypothesis are excluded at 99.95% confidence level.
