Summary

Story summary

Physicists from the MicroBooNE Collaboration ruled out the existence of a sterile neutrino with 95% certainty.
After ten years of data collection, no evidence of the elusive particle was found.
The sterile neutrino had been proposed to explain anomalies in neutrino behavior not aligning with the Standard Model.
The findings, published in Nature, will guide future experiments, including the Deep Underground Neutrino Experiment (DUNE).
