Measurement of Neutrino and Antineutrino Oscillations Using Beam and Atmospheric Data in MINOS

We report measurements of oscillation parameters from ν_μ and ν_μ disappearance using beam and atmospheric data from MINOS. The data comprise exposures of 10.71×10²⁰ protons on target in the ν_μ-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|=(2.41_-0.10+0.09)×10^-3 eV² and sin²(2θ)=0.950_-0.036+0.035. Allowing independent ν and ν oscillations, we measure antineutrino parameters of |Δm̄²|=(2.50_-0.25+0.23)×10^-3 eV² and sin²(2θ)=0.97_-0.08+0.03, with minimal change to the neutrino parameters.
