Solar neutrino oscillation parameters after first KamLAND results
Solar neutrino oscillation parameters after first KamLAND results
We analyze the energy spectrum of reactor neutrino events recently observed in the Kamioka Liquid Scintillator Antineutrino Detector (KamLAND) and combine them with solar and terrestrial neutrino data, in the context of two- and three-family active neutrino oscillations. In the $2\ensuremath{\nu}$ case, we find that the solution to the solar …
