Determining the neutrino mass hierarchy and CP-violation in NO nu A with a second off-axis detector

We consider a Super-NO nu A-like experimental configuration based on the use of two detectors in a long-baseline experiment as NO nu A. We take the far detector as in the present NO nu A 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-Cerenkov 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 theta(13). 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 nu A experiment could be achieved
