Fermi National Accelerator Laboratory is the premier particle physics lab in the United States. Founded as the National Accelerator Laboratory in 1967, it was renamed after physicist Enrico Fermi in 1974. Since its inception, Fermilab has been a world leader in particle physics, with discoveries including the bottom quark, top quark and tau neutrino, three of the elementary particles that make up our universe.

Fermilab is home to approximately 1,700 scientists, engineers, technicians and support staff, and hosts about 2,500 visiting scientists from around the world. The laboratory is managed by the Fermi Forward Discovery Group for the U.S. Department of Energy. More information can be found at www.fnal.gov.

Join us today for a scientific seminar at 3:30 p.m. CT to discuss MicroBooNE's new results released today in Nature! 🤩 The seminar will be streamed on our YouTube.

Scientists are closing the door on one explanation for a neutrino mystery that has plagued them for decades.

Researchers working on the MicroBooNE experiment at Fermilab announced today that they have found no evidence for a fourth type of neutrino. This so-called sterile neutrino was one possible explanation for anomalies seen by previous neutrino experiments.

With this new result, MicroBooNE has been able to rule out a single sterile neutrino explanation with 95% certainty.

The newest flagship building on the U.S. Department of Energy’s Fermi National Accelerator Laboratory campus, the Integrated Engineering Research Center (IERC), has been officially named the Helen Edwards Engineering Research Center in honor of the late Dr. Helen Edwards, a particle physicist at Fermilab for 40 years.

Helen Edwards was a towering figure in the world of accelerator science, renowned for leading the design, construction, commissioning and operation of Fermilab’s Tevatron accelerator. The Tevatron held the title of the world’s most powerful particle collider for 25 years and discovered the top quark in 1995 and the tau neutrino in 2000 — two of the three fundamental particles identified at Fermilab.

DUNE aims for gold 🏅

Exciting update for the Long-Baseline Neutrino Facility/Deep Underground Neutrino Experiment: Technicians marked the location where the neutrino beam from Fermilab will be aimed for #DUNEscience. This beam will travel 800 miles from Fermilab in Illinois to ‪@SanfordlabOrg‬ in South Dakota through stone and earth, no tunnel needed!

The international NOvA collaboration presented new results at the Neutrino 2024 conference on June 17. The collaboration doubled their neutrino data since their previous release, including adding a new low-energy sample of electron neutrinos!

NOvA aims to learn more about the ordering of neutrino masses. Physicists know that there are three types of neutrinos with different masses, but they don’t know the absolute mass, nor which is heaviest.Theoretical models predict two possible mass orderings, normal or inverted. In the normal ordering, there are two light neutrinos and one heavier neutrino; in inverted, there is one light neutrino and two heavier ones.

The new results are consistent with previous NOvA results, but with improved precision. The data favor the “normal” ordering of neutrino masses more strongly than before, but ambiguity remains around the neutrino’s oscillation properties.
