Shedding light on LMA-dark solar neutrino solution by medium baseline reactor experiments: JUNO and RENO-50

This is the authors' abstract. We don't add key points for this paper.

In the presence of Non-Standard neutral current Interactions (NSI) a new solution to solar neutrino anomaly with cos 2θ 12 < 0 appears. We investigate how this solution can be tested by upcoming intermediate baseline reactor experiments, JUNO and RENO-50. We point out a degeneracy between the two solutions when both hierarchy and the θ 12 octant are flipped. We then comment on how this degeneracy can be partially lifted by long baseline experiments sensitive to matter effects such as the NOvA experiment.
