Study of the eightfold degeneracy with a standard β-beam and a super-beam facility Original Research Article

The study of the eightfold degeneracy at a neutrino complex that includes a standard β-beam and a super-beam facility is presented for the first time in this paper. The scenario where the neutrinos are sent toward a megaton water Čerenkov detector located at the Fréjus laboratory (baseline 130 km) is exploited. The performance in terms of sensitivity for measuring the continuous (image and δ) and discrete (image and image) oscillation parameters for the β-beam and super-beam alone, and for their combination has been studied. A brief review of the present uncertainties on the neutrino and antineutrino cross-sections is also reported and their impact on the discovery potential discussed.
