Super Beams

High intensity conventional horn-focused neutrino beam produced by MW-class proton accelerator, “super beam”, provides opportunity to further develop neutrino physics, especially long baseline (LBL) oscillation experiments. Several super beam LBL experiments are proposed as next generation high sensitivity, high precision experiments before neutrino-factory era. Sensitivities of the experiments are one orders of magnitude or more higher than the current ones. The experiments and their physics potential are introduced.
