$\theta_{13}$, delta and the neutrino mass hierarchy at a gamma = 350 double baseline Li/B beta-Beam

We consider a β-Beam facility where 8Li and 8B ions are accelerated at γ = 350, accumulated in a 10 Km storage ring and let decay, so as to produce intense e and νe beams. These beams illuminate two magnetized iron detectors located at L 2000 Km and L 7000 Km, respectively. The physics potential of this setup is analysed in full detail as a function of the flux. We find that, for the highest flux considered (10 × 1018 ion decays per year per baseline), the sensitivity to θ13 reaches sin2 2θ13 ≥ 1 × 10−4; the sign of the atmospheric mass difference can be identified, regardless of the true hierarchy, for sin2 2θ13 ≥ 3 × 10−4; and, CP violation can be discovered in 70% of the δ-parameter space for sin2 2θ13 ≥ 10−3, having some sensitivity to CP violation down to sin2 2θ13 ≥ 2 × 10−4 for |δ| ~ 90°.
