Discovery brings scientists one step closer to solving century-old cosmic ray mystery

MicroBooNE experiment’s first results show no hint of a sterile neutrino
For more than a decade, scientists have wondered whether a theorized new particle, a fourth kind of neutrino called the sterile neutrino, might exist in our universe. Evidence of this would add a new particle to the physicists’ best theory, the Standard Model of Particle Physics. A new particle would be a radical shift in our understanding of the basic building blocks of the universe. MicroBooNE’s four new experimental results all show the same thing: no sign of the sterile neutrino. Instead, the results align with the Standard Model of Particle Physics. With sterile neutrinos further disfavored as the explanation for anomalies spotted in neutrino data, scientists are investigating other possibilities. Unexplained data point toward promising research areas and lead us to more fundamental truths about how physics works at the smallest level.

Particle detector at Fermilab plays crucial role in Deep Underground Neutrino Experiment
One of the DUNE near detector’s subdetectors, SAND, will detect neutrinos with an electronic calorimeter, which measures particle energy, and a tracker, which records particle momenta and charge. A second subdetector will use liquid argon to mimic the neutrino interactions in the far detector. The third will use gaseous argon. Working together, they will measure particles with more precision than other neutrino detectors have able been to achieve. Credit: DUNE collaboration
