MicroBooNE's two main physics goals are to investigate the MiniBooNE low-energy excess and neutrino-argon cross sections.
[5] MicroBooNE collected five years of physics data, ending its run in 2021 as the longest continually operating liquid argon time projection chamber to date.
The Fermilab press release accompanying the results [10] claimed that the electron hypothesis test dealt "a blow to a theoretical particle known as the sterile neutrino."
However, the accompanying commentary to the MicroBooNE papers, when they were published in Physical Review Letters, was entitled "Neutrino Mystery Endures.
"[11] The full parameter space of sterile neutrino models hinted at by MiniBooNE and other data remains still under investigation.
