Future Neutrino Long Baseline Experiments

Very soon a new generation of reactor and accelerator neutrino oscillation experiments-Double Chooz, Daya Bay, Reno and T2K-will seek for oscillation signals generated by the mixing parameter theta(13). The knowledge of this angle is a fundamental milestone to optimize further experiments aimed at detecting CP violation in the neutrino sector. Leptonic CP violation is a key phenomenon that has profound implications in particle physics and cosmology but it is clearly out of reach for the aforementioned experiments. Since late 90's, a world-wide activity is in progress to design facilities that can access CP violation in neutrino oscillation and perform high precision measurements of the lepton counterpart of the Cabibbo-Kobayashi-Maskawa matrix.
