Constraints on the solar Δm2 using Daya Bay and RENO data

Abstract

We demonstrate that the currently running short baseline reactor experiments, especially Daya Bay, can put a significant upper bound on Δm212. This novel approach to determining Δm212 can be performed with the current data of both Daya Bay and RENO and provides additional information on Δm212 in a different L/E range (∼0.5 km/MeV) for an important consistency check on the 3 flavor massive neutrino paradigm. Upper limits by Daya Bay and RENO and a possible lower limit from Daya Bay, before the end of 2020, will be the only new information on this important quantity until the medium baseline reactor experiment, JUNO, gives a very precise measurement in the middle of the next decade. In this study θ12 value is fixed since its impact on the Δm212 measurement is relatively small as discussed in the Appendix. © 2019 authors. Published by the American Physical Society.
