Title: Final Results from the Muon $g-2$ Experiment at Fermilab

Abstract: The anomalous magnetic moment of the muon ($a_{\mu} \equiv (g_{\mu} - 2)/2$) provides a strict test of the standard model of particle physics, as it can be both calculated and measured to extremely high precision. The Muon $g-2$ Experiment at Fermilab recently published its final results, in which $a_{\mu}$ was determined to a precision of 127 parts-per-billion via careful measurement of the spin precession of a stored muon beam in the $1.45$\,T field of a magnetic storage ring. This represents a more than four-fold improvement over the previous generation experimental result. This talk will present an overview of the experimental technique and analysis, some systematic evaluations that were performed in the lead up to the final publication, and a discussion of the current state of the standard model prediction and the tensions therein.
