KamLAND: reactor neutrino results and the future prospect

Junpei Shirai, Tohoku University, Japan
6008 Conference Room

The neutrino is one of the elementary particles, but unlike others it is much more mysterious with its tiny interactions and the mass being too light to be confirmed until very recently. Still, our world is known to be full of neutrinos coming from the sun, sky, etc., and even from the earth. Significant progress has been made in the last several years which has made clear the properties of the neutrino: the finite mass and the flavor conversion.
       The talk covers the recent results from KamLAND, Kamioka Liquid scintillator Anti-Neutrino Detctor, which made the first observation of the neutrino disappearance from distant power reactors. Also presented is near-future prospects of KamLAND for the real-time detection of terrestrial neutrinos and a challenge to 7Be solar neutrinos from the sun which would make a great contribution to geophysics and solar physics as well as particle physics.
