Abstract

We consider a Super-NO\ensuremathνA-like experimental configuration based on the use of two detectors in a long-baseline experiment as NO\ensuremathνA. We take the far detector as in the present NO\ensuremathνA proposal and add a second detector at a shorter baseline. The location of the second off-axis detector is chosen such that the ratio L/E is the same for both detectors, being L the baseline and E the neutrino energy. We consider liquid argon and water-\ifmmode \checkC\else \vC\fierenkov techniques for the second off-axis detector and study, for different experimental setups, the detector mass required for the determination of the neutrino mass hierarchy, for different values of \ensuremathθ₁₃. We also study the capabilities of such an experimental setup for determining CP-violation in the neutrino sector. Our results show that by adding a second off-axis detector a remarkable enhancement on the capabilities of the current NO\ensuremathνA experiment could be achieved.
