Understand

We present the first results of the Fermilab Muon g-2 Experiment for the positive muon magnetic anomaly $a_\mu \equiv (g_\mu-2)/2$.

The anomaly is determined from the precision measurements of two angular frequencies.
Intensity variation of high-energy positrons from muon decays directly encodes the difference frequency $\omega_a$ between the spin-precession and cyclotron frequencies for polarized muons in a magnetic storage ring.
The storage ring magnetic field is measured using nuclear magnetic resonance probes calibrated in terms of the equivalent proton spin precession frequency ${\tilde{\omega}'^{}_p}$ in a spherical water sample at 34.7$^{\circ}$C.

The value is based on evaluating hadronic vacuum polarization contributions via e + e − → hadrons e^{+}e^{-}\rightarrow\text{hadrons} data. Lattice QCD calculations of the hadronic vacuum polarization show promising improvements Aoyama et al. 2020 ; Chakraborty et al. 2018 ; Borsanyi et al. 2018 ; Blum et al. 2018 ; Giusti et al. 2019 ; Shintani and Kuramashi 2019 ; Davies et al. 2020 ; Gérardin et al. 2019 ; Aubin et al. 2020 ; Giusti and Simula 2019 ; Borsanyi et al. 2020 ; Lehner and Meyer 2020 . The lattice world average determined in Ref. Aoyama et al. 2020 is consistent with the data-driven result used for the number in the main text, but has a higher central value and larger uncertainty. Further scrutiny and improvements of lattice results are expected
