### First Results From Fermilab's Muon G-2 Experiment Strengthen ...

The first results from the Muon g-2 experiment hosted at Fermi National Accelerator Laboratory show fundamental particles called muons behaving in a way not predicted by the Standard Model of particle physics. These results confirm an earlier experiment of the same name performed at Brookhaven National Laboratory. Combined, the two results show strong evidence that our best theoretical model of the subatomic world is incomplete. One potential explanation would be the existence of undiscovered particles or forces. Apr 7, 2021 ... The Muon g-2 experiment sends a beam of muons into the storage ring, where they circulate thousands of times at nearly the speed of light. [ReadMore..]

### Status Of The Fermilab Muon $G-2$ Experiment

The muon anomalous magnetic moment, $a_μ= (g-2)/2$, is a low-energy observable which can be both measured and computed with very high precision, making it an excellent test of the Standard Model (SM) and a sensitive probe of new physics. Recent efforts improved the precision of both the theoretical prediction and the experimental measurement. On the theory side, the Muon $g-2$ Theory Initiative, an international team of more than 130 physicists, reached in 2020 a consensus on the SM prediction for $a_μ$. On the experimental side, the E989 Muon $g-2$ Collaboration at Fermilab (FNAL) published in April 2021 a new measurement of $a_μ$ from the Run-1 dataset (2018) with 0.46 ppm precision, corroborating the previous Brookhaven National Laboratory (BNL) measurement and increasing the discrepancy with the SM value to 4.2 standard deviations. In this paper, I will discuss the experimental setup and report on the current status of the experiment. Feb 23, 2022 ... Abstract: The muon anomalous magnetic moment, a_\mu = (g-2)/2, is a low-energy observable which can be both measured and computed with very ... [ReadMore..]
