"KamLAND: Neutrinos from Heaven and Earth"

Abstract

KamLAND (the Kamioka Liquid scintillator AntiNeutrino Detector) has recently reported observation of the disappearance of antineutrinos from distant nuclear power reactors in Japan. This result provides clear evidence for neutrino oscillations with manmade neutrino sources and precise constraints on the neutrino masses and mixing angles. The KamLAND measurement is inconsistent with all solutions to the solar neutrino problem except the “Large Mixing Angle” solution (assuming CPT invariance). In addition to future improvements in the precision of the reactor measurements, the KamLAND experiment will also provide measurements of geoneutrinos from the earth, can potentially observe neutrinos from supernovae and perhaps even the sun.  In the near future, KamLAND and other planned experiments will play a key role in precise studies of neutrino properties.
