Combined analysis of ?µ disappearance and ?µ ? ?e appearance in MINOS using accelerator and atmospheric neutrinos
journal contribution
posted on 2023-06-09, 07:52 authored by N E Devenish, Elisabeth FalkElisabeth Falk, Jeff HartnellJeff Hartnell, et al The MINOS CollaborationWe report on a new analysis of neutrino oscillations in MINOS using the complete set of accelerator and atmospheric data. The analysis combines the ?µ disappearance and ?e appearance data using the three-flavor formalism. We measure |?m^2 32| = [2.28–2.46] × 10-3 eV^2 (68% C.L.) and sin^2 ?23 = 0.35–0.65 (90% C.L.) in the normal hierarchy, and |?m^2 32| = [2.32–2.53] × 10-3 eV^2 (68% C.L.) and sin^2 ?23 = 0.34–0.67 (90% C.L.) in the inverted hierarchy. The data also constrain dCP, the ?23 octant degeneracy and the mass hierarchy; we disfavor 36% (11%) of this three-parameter space at 68% (90%) C.L.
