Neutrino Mass Difference Measurement (IMAGE) DOE/Fermi National Accelerator Laboratory Caption Neutrino oscillations depend on two parameters: the square of the neutrino mass difference, Δm2, and the mixing angle, sin22θ. MINOS results (shown in black), accumulated since 2005, yield the most precise known value of Δm2, namely Δm2 = 0.0024 ± 0.0001 eV2.
