Exploring leptonic CP violation with a Li/B β‐beam from CERN to Gran Sasso

We have considered a β‐beam setup which tries to leverage at most existing European facilities to boost high‐Q ions aiming at a far detector located at L = 732 km in the Gran Sasso Underground Laboratory. The average neutrino energy obtained from 8Li and 8B ions boosted at γ100 is in the range Ev ∈ [1,2] GeV, high enough to use a large iron detector of the MINOS type. We perform, then, a study of the neutrino and antineutrino fluxes needed to observe CP violation and to establish the neutrino mass hierarchy in a significant part of the parameter space.
