MicroBooNE

New results from the MicroBooNE experiment at Fermilab found no evidence of a hypothetical fourth flavor of neutrino.

An international collaboration of scientists working on the MicroBooNE experiment at Fermilab announced that they have found no evidence for a fourth type of neutrino, known as a sterile neutrino.

Scientists on the MicroBooNE experiment further ruled out the possibility of one sterile neutrino as an explanation for results from previous experiments. In the latest MicroBooNE result, the collaboration used one detector and two beams to study neutrino behavior, ruling out the single sterile neutrino model with 95% certainty.

A recent Physical Review Letters publication presents a thorough analysis of MicroBooNE detector data, investigating the anomalous surplus of neutrino-like events detected by the preceding MiniBooNE experiment.

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.
