Degeneracies at a beta-Beam and a Super-Beam Facility

Abstract

The presence of degeneracies can considerably worsen the measure of the neutrino oscillation parameters ${\theta }_{13}$ and $\delta$. We study the physics reach of a specific ``CERN'' setup, using a standard $\beta$-Beam and Super-Beam facility. These facilities have a similar sensitivity in both parameters. Their combination does not provide any dramatic improvement as expected due to their almost identical L/E ratio. We analyse if adding the correspondent disappearance channels can help in reducing the effect of degeneracies in the $({\theta }_{13},\delta )$ measure.
