Mass hierarchy determination using current and upcoming neutrino experiments

Determination of mass hierarchy is a crucial open ended question in neutrino physics today. In the wake of recent T2K, MINOS and DChooz results which support a high best-fit to θ13, it is worthwhile to explore the potential of the upcoming and already running neutrino experiments for determining mass hierarchy. We consider the long baseline experiments NOνA and T2K and the reactor neutrino experiments Daya Bay, DChooz and RENO. In our analysis we find out that NOνA by itself is insufficient and would require another long baseline experiment such as T2K. This work assumes that by the time reactor neutrino experiments are over, we will have a precise θ13 information. Final results are presented as hierarchy exclusion plots in sin2 2θ13 − δCP plane.
