Summary

Story summary

An international team of physicists, including Rutgers University researchers, published findings in Nature challenging the existence of a sterile neutrino.
The MicroBooNE experiment at Fermilab, using a liquid-argon detector, ruled out the sterile neutrino hypothesis with 95% confidence after ten years of data.
The results narrow the search for new physics beyond the Standard Model while paving the way for future experiments such as the Deep Underground Neutrino Experiment (DUNE).
