Muon g-2

From RTS (Swiss Broadcasting Corporation), Sept. 7, 2023: Fermilab’s August 10 announcement indicated the muon does not behave as theory predicts. Professor Tobias Golling, from the particle physics department at the University of Geneva, explains in a video that there are two possibilities to explain the observed discrepancy.

India is recognizing three young Fermilab scientists from Kolkata who are among the 200 scientists from the Muon g-2 collaboration searching for new physics by studying muons.

NPR’s Ayesha Rascoe speaks to Esra Barlas Yücel, a researcher at University of Illinois at Urbana-Champaign, about Fermilab’s most precise measurements of the muon particle’s magnetic wobble.

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.

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.

Scientists working on Fermilab’s Muon g-2 experiment released the world’s most precise measurement yet of the magnetic moment of the muon, bringing particle physics closer to the ultimate showdown between theory and experiment that may uncover new particles or forces.

A proponent of mentorship and inclusion, Argonne National Laboratory physicist Peter Winter brings his experience with managing and collaborating among the researchers of the Muon g-2 experiment to the position of spokesperson.
