Optimization of neutrino oscillation facilities for large \theta_{13}

Understand

Up to now, future neutrino beam experiments have been designed and optimized in order to look for CP violation, \theta_{13} and the mass hierarchy under the conservative assumption that \theta_{13} is very small.

• However, the recent results from T2K and MINOS favor a \theta_{13} which could be as large as 8^{\circ}.
• In this work, we propose a re-optimization for neutrino beam experiments in case this hint is confirmed.
• By switching from the first to the second oscillation peak, we find that the CP discovery potential of future oscillation experiments would not only be enhanced, but it would also be less affected by systematic uncertainties.
