No sterile neutrinos after all, say MicroBooNE physicists
- MicroBooNE finds no evidence of sterile neutrinos, confirming a null result for this hypothesis.
- The latest paper confirms there are no oscillations into a sterile neutrino in MicroBooNE data.
- Fermilab’s search now shifts to alternative explanations and new experiments for the earlier anomalies.
- The Deep Underground Neutrino Experiment (DUNE) is under construction to study high-energy neutrinos.
- MicroBooNE’s size enabled precise measurements, aiding future large-scale detectors like DUNE.
- MicroBooNE used a liquid-argon time projection chamber to analyze neutrino interactions.
- MicroBooNE’s five-year data set (2015–2021) underpins the null result for sterile neutrinos.
- The findings guide ongoing and future neutrino research within the SBN program and DUNE.
- The Nature paper detailing MicroBooNE’s results is published with DOI 10.1038/s41586-025-09757-7.
