摘要: The number of sigma confidence in a determination the neutrino mass hierarchy may be obtained from statistic Delta chi squared. However, as is discrete variable, this not given by usual square root formula. We review simple Bayesian formula for sensitivity to that can median experiment function compare analytical 6 years simulated data JUNO together with 4% (1%) effective atmospheric splitting disappearance channel at MINOS (NOvA). find squared 11 (20) yielding 2.6 (3.9 sigma). However when unknown nonlinear energy response detector included our analysis significance degrades considerably. This degradation eliminated dividing single into near and far same total target mass. A further advantage second that, even while reactor runs, decay rest single, high intensity, continuously running pion source close one detectors, such described DAEdALUS project, determine leptonic CP-violating phase delta.
