Abstract

Recently, three reactor neutrino experiments, Daya Bay, Double Chooz and RENO have directly measured the neutrino mixing angle θ13. In this Letter, another important oscillation parameter, effective δm312 (=δm~312) is measured using baseline dependence of the reactor neutrino disappearance. A global fit is applied to publicly available data and δm~312=2.95-0.61+0.42×10-3 eV2, sin22θ13=0.099-0.012+0.016 are obtained by setting both parameters free. This result is complementary to δm~312 to be measured by spectrum shape analysis. The measured δm~312 is consistent with δm~322 measured by νμ disappearance in MINOS, T2K and atmospheric neutrino experiments within errors. The minimum χ2 is small, which means the results from the three reactor neutrino experiments are consistent with each other. © 2013 Elsevier B.V.
