Abstract

We report on a new analysis of neutrino oscillations in MINOS using the complete set of accelerator and atmospheric data. The analysis combines the νμ disappearance and νe appearance data using the three-flavor formalism. We measure |Δm322|=[2.28-2.46]×10-3eV2 (68% C.L.) and sin2θ23=0.35-0.65 (90% C.L.) in the normal hierarchy, and |Δm322|=[2.32-2.53]×10-3eV2 (68% C.L.) and sin2θ23=0.34-0.67 (90% C.L.) in the inverted hierarchy. The data also constrain δCP, the θ23 octant degeneracy and the mass hierarchy; we disfavor 36% (11%) of this three-parameter space at 68% (90%) C.L.
