By combining its neutrino and antineutrino data sets, MINOS has provided first constraints on the spectrum of neutrino masses (represented by the sign of Δm2), the CP-violating phase δ, and whether muon or tau neutrinos are more strongly mixed with the so-called ν3 mass state (indicated by θ23). The relative goodness of each scenario is given along the vertical axis in terms of a difference of log-likelihoods. The parameter Δm2 and the angles θ13 and θ23 relate to the relative…
