From Popular Science, August 17, 2023: Breaking the Standard Model would be one of the biggest moments in particle physics history. The Muon g-2 collaboration reported that the muon doesn’t always look like physicists expect it to look, but the collaboration isn’t done. Once they analyze all the remaining data, physicists believe they can make their g minus 2 estimate twice as precise again.

Plans are moving ahead for the liquid nitrogen refrigeration system which will use liquid nitrogen to cool the 17,500 tons of liquid argon that will fill the neutrino detectors at the Long Baseline Neutrino Facility in the Sanford Lab. The system is expected to be built by 2026, and operational underground by the end of 2026 to support the installation of some detector elements, and the operations of the full facility starting in early 2028.
From Le Monde, August 16, 2023: The characteristics muons were analyzed in an ongoing experiment by the Muon g-2 collaboration at Fermilab and the results are shaking up the theory community.
From Universe Today, August 14, 2023: In a recent announcement, scientists at Fermilab and the international Muon g-2 collaboration made the world’s most precise measurement of the muon’s anomalous magnetic moment, improving the precision of their previous measurements by a factor of 2. With this measurement, the collaboration has achieved its goal of decreasing systematic uncertainties caused by experimental imperfections.
From Univision, August 11. 2023 (Right click to translate to English): The Muon g-2 results announced last week confirm muons did not behave as predicted by the current theory of physics, the Standard Model. The announcement brings physicists closer to discoveries such as whether there are more types of matter and energy that make up the universe than have been accounted for.
From The Conversation, Aug. 10, 2023: The new results of the Muon g-2 experiment are summarized by a group of Postdocs from the University of Liverpool. The latest results examined four times as many muons as the 2021 result, cutting the total uncertainty by a factor of two. This makes the measurement the most precise determination of the muon’s wobble ever made on Muon g-2.
From the Chicago Tribune, Aug. 10, 2023: This week Fermilab hosted the first U.S. Quantum Information Science school for 150 students, including scientists, researchers, college students and industry professionals. The program aims to educate the next generation of researchers on quantum device design and fabrication; quantum computing algorithms; quantum sensing; and cryogenics.
From Interesting Engineering, Aug. 9, 2023: For more than a decade, SLAC has been preparing to power the world’s most powerful X-ray free electron laser by getting electrons to fly through a new superconducting accelerator called the Linac Coherent Light Source II. Fermilab is one of the four national labs to contribute to the engineering of this powerful superconducting X-ray machine.
From the The Globe and Mail (Canada), Aug. 5, 2023: Scientists and researchers at SNOLAB are assembling a new experiment known as the Super Cryogenic Dark Matter Search to help solve the mystery of, what is the dark of dark matter? Fermilab associate scientist, Daniel Baxter who worked at the SNOLAB facility two kilometers beneath the Earth’s surface, weighs in.
From Pacific Northwest National Laboratory, July 25, 2023: PNNL scientists and a team of university and national laboratory collaborators recently published a paper detailing a new detector design that can be fine-tuned to increase sensitivity to physics beyond the original DUNE concept.
