Neutrino mass hierarchy and $\theta_{13}$ with a magic baseline beta-beam experiment

High Energy Physics - Phenomenology 2008-11-26 v2 High Energy Physics - Experiment

Abstract

We underscore the physics advantage of an experiment where neutrinos produced in a beta-beam facility at CERN are observed in a large magnetized iron calorimeter (ICAL) at the India-based Neutrino Observatory (INO). The CERN-INO distance is close to the so-called "magic" baseline which helps evade some of the parameter degeneracies and allows for a better measurement of the neutrino mass hierarchy and θ13\theta_{13}. We expound the possibility of using radioactive 8B^8B and 8Li^{8}Li as the source isotopes for the \nue\nue and \anue\anue beta-beam, respectively, and show that very good sensitivity to both the mass hierarchy and θ13\theta_{13} is possible with a boost γ\gamma in the 250-500 ballpark.
