Scientists have announced the world's most precise measurement of the parameters that govern antineutrino oscillations. This mass difference parameter, called "delta m squared", is smaller by approximately 40 percent for neutrinos than for antineutrinos. However, there is a still a five percent probability that delta m squared is actually the same for neutrinos and antineutrinos. Theorists expected the two values to be the same.
