An international team of theoretical physicists have published their calculation of the anomalous magnetic moment of the muon. Their work expands on a simple yet richly descriptive equation that revolutionized physics almost a century ago and that may aid scientists in the discovery of physics beyond the Standard Model. Now the world awaits the result from the Fermilab Muon g-2 experiment.
From El Dia, May 18, 2020: Los esperados resultados del experimento Muon g-2 del Fermilab probablement proporcionarán algunas ideas sobre un área donde Modelo Estándar podría fallar.
From APS Physics, May 14, 2020: Particle physicists are faced with a growing list of anomalies — experimental results that conflict with the Standard Model but fail to overturn it for lack of sufficient evidence. These include the muon anomaly, which scientists on Fermilab’s Muon g-2 experiment are studying. Fermilab scientist Chris Polly is featured in this article.
From Gizmodo, May 4, 2020: Fermilab’s Muon g-2 experiment is featured in this piece on today’s biggest discoveries in physics, which come from huge collaborations of scientists working on enormous apparatuses.
From Argonne National Laboratory, May 5, 2020: Using Argonne’s supercomputer Mira, researchers have come up with newly precise calculations aimed at understanding a key gap between physics theory and measurements by the Muon g-2 experiment
From Gizmodo, Jan. 25, 2020: Physicists have found all of the particles and forces that the Standard Model describes, but there are still countless mysteries in the universe that the theory fails to explain. Various experiments are now probing the Standard Model for cracks, and this year, scientists hope to unveil a measurement from one of them, the Muon g-2 experiment, a measurement that might break from the theory.
From Nature, Dec. 20, 2019: Fermilab should unveil long-awaited results from Muon g–2, a high-precision measurement of how muons — more-massive siblings of electrons — behave in a magnetic field. Physicists hope that slight anomalies could reveal previously unknown elementary particles.
From Gizmodo, Oct. 23, 2019: Ahead lies a whole frontier in particle physics of grand unsolved mysteries, including why there’s more matter than antimatter in the universe, what the true identity of dark matter and dark energy is, or how the strange, ultraweak neutrino particles ended up so ghostly. The Fermilab-hosted DUNE and Muon g-2 experiments are among those looking for answers.
From Johannes Gutenberg University Mainz, Sept. 30, 2019: Johannes Gutenberg University Mainz strengthens its relationship with Fermilab by joining the Muon g-2 collaboration. Muon g-2 aims at a determination of the muon anomalous magnetic moment with the unprecedented precision of 140 part per billion. This fourfold improvement over the last experiment, performed at Brookhaven National Laboratory more than 15 years ago, will allow to scientists test the resulting more than 3 standard deviation discrepancy between experiment and the prediction of the Standard Model in its current form.
From Back Reaction, June 13, 2019: The so-called muon g-2 anomaly is a tension between experimental measurement and theoretical prediction. The most recent experimental data comes from a 2006 experiment at Brookhaven National Lab. A new experiment is now following up on the 2006 result: The Muon g-2 experiment at Fermilab.
