A global fit determination of effective dm312 from baseline dependence of reactor ?-e disappearance
journal contribution

In this Letter, another important oscillation parameter, effective dm312 (=dm~312) is measured using baseline dependence of the reactor neutrino disappearance. A global fit is applied to publicly available data and dm~312=2.95-0.61+0.42×10-3 eV2, sin22?13=0.099-0.012+0.016 are obtained by setting both parameters free. This result is complementary to dm~312 to be measured by spectrum shape analysis. The measured dm~312 is consistent with dm~322 measured by ?µ disappearance in MINOS, T2K and atmospheric neutrino experiments within errors. The minimum ?2 is small, which means the results from the three reactor neutrino experiments are consistent with each other. © 2013 Elsevier B.V.
