Abstract

We report measurements of oscillation parameters from νμ and ν¯μ disappearance using beam and atmospheric data from MINOS. The data comprise exposures of 10.71×1020 protons on target in the νμ-dominated beam, 3.36×1020 protons on target in the ν¯μ-enhanced beam, and 37.88 kton yr of atmospheric neutrinos. Assuming identical ν and ν¯ oscillation parameters, we measure |Δm2|=(2.410.10+0.09)×103eV2 and sin2(2θ)=0.9500.036+0.035. Allowing independent ν and ν¯ oscillations, we measure antineutrino parameters of |Δm¯2|=(2.500.25+0.23)×103eV2 and sin2(2θ¯)=0.970.08+0.03, with minimal change to the neutrino parameters.
