Abstract
We update our study of neutrino mass hierarchy determination using a high statistics reactor \({\overline \nu_e}\) experiment in the light of the recent evidences of a relatively large non-zero value of θ 13 from the Daya Bay and RENO experiments. We find that there are noticeable modifications in the results, which allow a relaxation in the detector’s characteristics, such as the energy resolution and exposure, required to obtain a significant sensitivity to, or to determine, the neutrino mass hierarchy in such a reactor experiment.
