Title: Constraints on the solar Δ m 2 using Daya Bay and RENO data

Abstract

Here, we demonstrate that the currently running short baseline reactor experiments, especially Daya Bay, can put a significant upper bound on $$\Delta m^2_{21}$$. This novel approach to determining $$\Delta m^2_{21}$$ can be performed with the current data of both Daya Bay \& RENO and provides additional information on $$\Delta m^2_{21}$$ in a different $L/E$ range ($$\sim$$ 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 $$\theta_{12}$$ value is fixed since its impact on the $$\Delta m^2_{21}$$ measurement is relatively small as discussed in the Appendix.
