Results from MINOS and NOvA
The MINOS experiment, operating in the NuMI beam since 2005, has provided the most precise measurement of the atmospheric mass splitting $|Δm^2_{32}|$, and the recent combination of the $ν_μ$, $ν_e$, and atmospheric neutrino samples has provided some evidence of non-maximal mixing, and hints about the neutrino mass hierarchy and the $θ_{23}$ octant. Construction of the NOvA experiment, situated off-axis in the upgraded NuMI beam, is almost complete. Over the coming years it will have significant power to probe the questions of the mass hierarchy, $θ_{23}$ octant, and the possibility of $\mathcal{CP}$ violation in the lepton sector. This paper gives an overview of the results from MINOS, and of the sensitivity of the NOvA experiment.
