MicroBooNE

Wilson Hall behind text: 2021 at Fermilab

For Fermilab, 2021 was a momentous year that included major science results, construction progress, record-setting equipment, and more. Get a quick recap of some 2021 milestones in this video, which features drone and timelapse footage from around the lab.

From Wired, December 5, 2021: Years of conflicting measurements have led physicists to propose a “dark sector” of invisible particles that could explain dark matter and the universe’s expansion. Now, four analyses released yesterday by the MicroBooNE experiment from Fermilab and another recent study from the IceCube detector at the South Pole both suggest that these more complex neutrino theories may be on the right track—though the future remains far from clear.

From Universe Today, November 5, 2021: Neutrinos might make up a small portion of dark matter, but most dark matter must be something else. Because neutrinos are so close to satisfying the properties of dark matter, some scientists have argued dark matter might be a yet undiscovered variety known as sterile neutrinos.What did Fermilab’s newest experiment MicroBooNE see?

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.
