Already beyond the Standard Model

In its quest to understand why matter exists, the flagship neutrino experiment hosted by Fermilab is constructing an enormous next-generation liquid-argon-based detector a mile underground. The Deep Underground Neutrino Experiment is building on the successes of previous liquid-argon experiments, promising measurements of unprecedented precision over a wide range of energies that will bring significant new insights into the nature of the universe.

The Short-Baseline Near Detector has logged the largest sample of neutrino interactions in liquid argon in the world. Newly elected, Andrzej Szelc will co-lead SBND during the next phase of the experiment.

On July 21, 2000, the DONUT collaboration at Fermilab announced the first direct evidence for tau neutrinos. The particles remain elusive to this day, but physicists continue to seek new ways of studying them.
