The Muon g-2 Experiment [Slides]
- University of Massachusetts, Amherst, MA (United States)
$$a_{\mu} \equiv (g-2)/2$$, most recently at Brookhaven National Lab (E821) in the early 2000s, differ from theoretical calculations by nearly 3.5\,$$\sigma$$. To address this discrepancy, the Muon $g-2$ Experiment at Fermilab (E989) has been designed to determine $$a_{\mu}$$ to a precision of 140 parts per billion, a four-fold improvement over the E821 measurement. This improved precision presents an excellent opportunity to uncover new physics beyond the standard model (BSM), and at minimum constrain BSM models. The E989 experiment is currently taking physics-quality data, to date having recorded nearly 60\% more statistics than was obtained at Brookhaven. An overview of the experimental technique will be discussed, along with an update of the run progress and selected hardware performance and analysis highlights.
