Neutrino oscillation experiments have measured precisely at few percent levels the mass-squared differences ($\mathrm{\ensuremath{\Delta}}{m}_{21}^{2}$, $\mathrm{\ensuremath{\Delta}}{m}_{31}^{2}$) of three neutrino mass eigenstates, and leptonic mixing angles (${\ensuremath{\theta}}_{12}$, ${\ensuremath{\theta}}_{13}$, ${\ensuremath{\theta}}_{23}$) by utilizing both antineutrino oscillations.
