Our accelerator team has met all of this year’s beam delivery goals, including those for NOvA, the Short-Baseline Neutrino program, and the new Muon Campus.

The observation occurred just two hours after the lab’s accelerator complex switched to antineutrino delivery mode.

NOvA scientists have seen evidence that one of the three neutrino mass states might not include equal parts of muon and tau flavor, as previously thought. Scientists refer to this as “nonmaximal mixing,” and NOvA’s result is the first hint that this may be the case for the third mass state.
