Abstract

We report measurements of oscillation parameters from νμ and ν̅ 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 ν̅ μ-enhanced beam, and 37.88 kton yr of atmospheric neutrinos. Assuming identical ν and ν̅ oscillation parameters, we measure |Δm2|=(2.41-0.10+0.09)×10-3  eV2 and sin⁡2(2θ)=0.950-0.036+0.035. Allowing independent ν and ν̅ oscillations, we measure antineutrino parameters of |Δm̅ 2|=(2.50-0.25+0.23)×10-3  eV2 and sin⁡2(2θ̅ )=0.97-0.08+0.03, with minimal change to the neutrino parameters.
