The Department of Energy has formally approved the start of full construction for the PIP-II project, an upgrade to the Fermilab accelerator complex that includes a new linear accelerator. PIP-II is an essential enhancement that will power the world’s most intense high-energy neutrino beam. It is the first particle accelerator built in the United States with significant contributions from international partners.

As this year’s composer-in-residence, they will create musical pieces in concert with Fermilab’s scientists.

The bison population is growing as the birth ushers in spring.

For the Muon g-2 experiment, researchers create billions of muons to study their surprising properties.

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.

Scientists of the Collider Detector at Fermilab collaboration have achieved the most precise measurement to date of the mass of the W boson, one of nature’s force-carrying particles. The measured value shows tension with the value expected based on the Standard Model of particle physics.

The two institutions have signed an agreement to collaborate on research in support of one of the largest particle physics experiments in the world: DUNE, hosted by Fermilab.

Beginning March 28, Fermilab will again be open to the public for outdoor activities, such as biking, hiking, running and viewing the bison herd.

The Mu2e experiment at Fermilab will look for a never-before-seen subatomic phenomenon that, if observed, would transform our understanding of elementary particles: the direct conversion of a muon into an electron. An international collaboration of over 200 scientists is building the Mu2e precision particle detector that will hunt for new physics beyond the Standard Model.

The career of Elaine McCluskey, who most recently served as project manager constructing the future facility for the Deep Underground Neutrino Experiment, has had a lasting impact.
