Muon g-2

In recent years, a new SM prediction of the muon g-2 has emerged that questions whether the discrepancy exists at all, suggesting that there is no new physics in the muon. Alex Keshavarzi, a member of the Muon g-2 Experiment and the Muon g-2 Theory Initiative, discusses what is next for the final result for g-2 in 2025.

In the quest to understand the fundamental forces that govern our universe, the Standard Model of particle physics has long stood as the cornerstone. Recent experimental discrepancies like those from Fermilab’s Muon g-2 experiment, have stirred the physics community, suggesting that the muon’s behavior under magnetic fields might not fully align with Standard Model prediction.

Brynn Kristen MacCoy’s work on improving beam dynamics has helped Muon g-2 researchers better understand and account for the behavior of the muon beam.

The unusually large Muon has threatened the Standard Model for decades, but new data parks the particle inside the confines of established physics. The BMW Collaboration’s recently posted research suggests the difference between the muon’s predicted anomalous magnetic moment and that predicted by the Standard Model is not as large as previous findings suggested.

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.

Interesting Engineering lists the top seven amazing innovations that pushed the boundaries of science and technology in 2023. Included in this line up is the latest announcement from the Muon g-2 collaboration with more evidence of a new force of nature that could revolutionize our understanding of the universe.

Fermilab research and announcements have helped promote the mystery of muons by studying how they wobble as they move through the magnetic ring. With science announcements in 2021 and 2023, science interested readers are wanting to learn more about the heavy cousins of electrons that are constantly raining down on Earth’s surface.

The Muon g-2 collaboration recently reported a new measurement of the so-called positive muon magnetic moment anomaly to a precision of 140 parts per billion. The collaboration’s findings are published in the journal Physical Review Letters.
