Poster Summary: An Alternative Method for Neutrino Mass Hierarchy Determination in JUNO

March 15, 2017

(by Fatma Sawy) The poster illustrates an alternative method of determining the neutrino mass ordering in medium baseline experiments with reactor antineutrinos. The method introduces an estimator so called “F-estimator”. That is the summation of total number of events in well defined energy intervals that correspond to the different oscillation pattern in two mass ordering cases as shown in Fig. 1.
