A minimal Beta Beam with high-Q ions to address CP violation in the leptonic sector

Understand

In this paper we consider a Beta Beam setup that tries to leverage at most existing European facilities: i.e.

• a setup that takes advantage of facilities at CERN to boost high-Q ions (8Li and 8B) aiming at a far detector located at L = 732 Km in the Gran Sasso Underground Laboratory.
• The average neutrino energy for 8Li and 8B ions boosted at \gamma ~ 100 is in the range E_\nu = [1,2] GeV, high enough to use a large iron detector of the MINOS type at the far site.
• We perform, then, a study of the neutrino and antineutrino fluxes needed to measure a CP-violating phase delta in a significant part of the parameter space.
