MicroBooNE

Researchers at the University of Oxford and the MicroBooNE collaboration have recently performed the first ever measurement of electron neutrino interactions on argon producing outgoing charged pions. The findings were reported in a cover article of Physical Review Letters.

To determine whether sterile neutrinos exist, researchers at Fermilab have constructed two new detectors as part of the Short-Baseline Neutrino (SBN) Program that they hope will resolve the situation once and for all.

The MicroBooNE collaboration at Fermilab has released a new analysis of their neutrino data. The result provides constraints on a model that assumes the existence of a sterile neutrino to explain anomalies in neutrino measurements by other experiments.

Physicists take on the mystery of the missing (and extra) neutrinos.

From the Department of Energy Office of Science, July 13, 2022: DOE announced $78 million in funding for 58 research projects that will spur new discoveries in high energy physics. The announcement covers a wide range of topics at the frontiers of particle physics, including Fermilab’s Muon g-2 and the MicroBooNE experiments.

For the first time, physicists extracted the detailed “energy-dependent neutrino-argon interaction cross section,” a key value for studying how neutrinos change their flavor.

Toups now co-leads the precision neutrino experiment through its analysis phase, along with Justin Evans of the University of Manchester.

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.
