Experiments performed in the last ten years provide strong evidence that neutrinos are particles with mass and that the neutrino states that couple through the weak interaction are mixtures of mass eigenstates. KamLAND is a 1000 ton scintillation detector located deep underground in western Japan.
KamLAND detects anti neutrinos from Japanese nuclear reactors hundreds of kilometers away. New results published this month provide the most direct evidence we have for neutrino oscillations. I will review the present understanding of neutrino mass and mixing in light of the new results form KamLAND and describe what we expect future neutrino experiments to reveal.
