From Scientific American, November 4, 2021: Physicists have wondered if neutrino particles come in a mysterious fourth variety. Now new experimental findings complicate the question. Physicists have wondered if neutrino particles come in a mysterious fourth variety. The MicroBooNE experiment findings announced last week by Fermilab heightened the mystery of why too many particles showed up in a detector during an experiment on the 1990s.
From Forbes, October 27, 2021: Fermilab’s Don Lincoln discusses the journey of the hypothetical sterile neutrino and the results of the MicroBooNE experiment hosted at Fermilab. Have sterile neutrinos been ruled out?
From Yale News, October 27, 2021: On Oct. 27, the international MicroBooNE collaboration announced the first results of MicroBooNE’s search for an anomaly that could have indicated a fourth type of neutrino, a subatomic particle considered a fundamental building block of matter.
From the BBC, October 27, 2021: Yesterday, the MIcroBooNE collaboration opened a new chapter in physics with the announcement of their results; the search failed to find the particle, known as the sterile neutrino.
Four complementary analyses by Fermilab’s MicroBooNE show no signs of a theorized fourth kind of neutrino known as the sterile neutrino. Its existence is considered a possible explanation for anomalies seen in previous physics experiments.
From the Daily Herald, September 30, 2021: From Glenbrook South high school to the deputy head of the Neutrino Division, an interview with Fermilab rock star Sam Zeller.
Back when it was theorized, scientists weren’t sure they would ever detect the neutrino. Now scientists, including some at Fermilab, are searching for a version of the particle that could be even more elusive.
From Queen Mary University of London, April 26, 2021: Fermilab scientist Dr. Kirsty Duffy was awarded the Ernest Rutherford Fellowship from the Science and Technology Facilities Council (STFC) to establish a new research group working on MicroBooNE at Queen Mary University of London. Duffy will continue to host the Even Bananas video series which explores neutrinos until the end of the year.
From Science Magazine (UK), June 9, 2021: Brookhaven scientists have developed new ways for the MicroBooNE detector at Fermilab to filter out cosmic ray tracks to pinpoint elusive neutrino interactions with unprecedented clarity.
