Very Long Baseline Neutrino Oscillations, The BNL VLBNO Concept

A wide energy-band neutrino beam sent over a very long baseline to a massive detector can break the degeneracies in the neutrino oscillation parameters. It can measure the disappearance parameters with precision and determine the mass hierarchy. If θ 13 is large enough the CP violating phase can be measured with neutrino running alone and anti-neutrino running can confirm CPV and improve the parameter measurements. Brookhaven National Laboratory is pursuing such an experiment.
