CP violation from a combined Beta Beam andElectron Capture neutrino experiment

摘要

We consider the proposal of a facility comprising a hybrid setup for a neutrino beam which combines an electron capture decay with a β~+ decay from the same radioactive ion with the same boost. We study the sensitivity to the mixing angle θ_(13) and the CP-phase, the CP discovery potential and the reach to determine the type of neutrino mass hierarchy. The analysis is performed for different boosts and baselines demonstrating that the combination of the two decay channels, with different neutrino energies, achieves remarkable results.
