Combined Analysis of ν_μ Disappearance and ν_μ→ν_e Appearance in MINOS Using Accelerator and Atmospheric Neutrinos

Creators

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 ν_μ disappearance and ν_e appearance data using the three-flavor formalism. We measure |Δm^2_(32)|=[2.28–2.46]×10^(−3)  eV^2 (68% C.L.) and sin^2θ_(23)=0.35–0.65 (90% C.L.) in the normal hierarchy, and |Δm^2_(32)|=[2.32–2.53]×10^(−3)  eV^2 (68% C.L.) and sin2θ23=0.34–0.67 (90% C.L.) in the inverted hierarchy. The data also constrain δ_(CP), the θ_(23) octant degeneracy and the mass hierarchy; we disfavor 36% (11%) of this three-parameter space at 68% (90%) C.L.
