Physicists use particle accelerators to replicate the early Universe’s conditions, revealing insights from the Big Bang to the formation of atoms. Data generated in particle physics experiments and theoretical physics can offer a glimpse into the earliest moments of the cosmos.

A collaboration scientists working on the Broadband Reflector Experiment for Axion Detection recently released their first results in the search for dark matter. Although they did not find dark matter, they narrowed the constraints for where it might be and demonstrated a unique approach that may speed up the search for the mysterious substance, at relatively little space and cost.

The researchers identified the origin of discrepancies in recent predictions of the muon’s magnetic moment. Their findings could contribute to the investigation of dark matter and other aspects of the new physics.

With the most recent P5 report, particle physicists have come together to chart a course for the next decade which includes focus on the international DUNE experiment taking place at Fermilab and in Lead, South Dakota.

An accelerator known as a muon collider could revolutionize particle physics—if it can be built. The December 2023 P5 report calls for R&D on a muon collider, stating, “This is our muon shot.” A muon collider could fit on the campus of Fermilab, enabling the U.S. to reclaim the lead in the continuing competition for the highest energy collider.

A new economic impact study shows the growing positive effects on economies in the U.S. through operations conducted by Fermi National Accelerator Laboratory. In Illinois and South Dakota, positive ripple effects from Fermilab spending contributed $1.6 billion in economic output during fiscal year 2022 and supported 7,242 jobs.

As excavation of the underground facilities for DUNE nears completion, crews are now working on laying concrete floors and spraying shotcrete on the walls of the caverns. The next priority is to prepare the south cavern for cryostat erection by installing sprinklers, fire alarms, an elevator, and overhead cranes

The CMS collaboration announced the observation of two photons creating two tau leptons in proton–proton collisions. This is the first time this process has been seen in proton–proton collisions using the precise capabilities of the CMS detector. It is also the most precise measurement of the tau’s anomalous magnetic moment and offers a new way to constrain the existence of new physics.

Fermilab’s 2024 Inventor Recognition Ceremony celebrated patents and ideas from Fermilab employees with notable guests. In 2023, 12 new patents were issued with 16 inventors associated with those patents working at Fermilab.

Rigging crews at SURF are performing a series of tests using a large wooden model L-beam built to the same scale as one of the huge steel components that arrived in South Dakota in January after being shipped from Spain. The tests are being done in anticipation of lowering the real thing down the shaft to the underground 4850 level.
