Current understandings of neutrino-nucleon interactions rely on data from experiments in the 1970s and ’80s. However, by using lattice quantum chromodynamics to predict stronger neutrino-nucleon interactions, scientists can determine oscillation properties of the elusive neutrinos in Fermilab’s DUNE experiment and other neutrino oscillation experiments.
From Quanta, October 28, 2021: In 1993, Los Alamos National Laboratory saw hints of a fourth kind of neutrino which led to MiniBooNE. Now the results of MicroBooNE reveal sterile neutrinos alone cannot account for the MiniBooNE anomaly and the results are consistent with the possibility that only half of MiniBooNE’s events are due to neutrino oscillations.
The NOvA collaboration has released the result of its latest measurement of neutrino oscillations. The results provide greater insight into neutrino properties, specifically mass ordering and charge parity symmetry.
DUNE’s near detector, located at Fermilab, will take vital measurements of neutrino beam energy and composition before it reaches the experiment’s far detector in South Dakota. Its unmatched precision measurements will offer its own opportunities for the discovery of new physics.
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.
