The anomalous magnetic moment of baryons in cavity QCD
… in cavity QCD to order as that contribute to the magnetic moment are calculated. The calculations are performed for massive quarks so a mass renormalisation scheme has been developed to cope with the new divergences this brings into the self-energy insert diagrams. The results of this work show …

The anomalous magnetic moment of the nucleon in cavity QCD
… All corrections to order eg² in the electromagnetic and strong coupling constants which contribute to the magnetic moment of a baryon are generated using this formalism. The O(eg²) radiative corrections to the magnetic moment of the nucleon are calculated here in an arbitrary covariant …

A Measurement of the Anomalous Magnetic Moment of the Negative Muon to 0.7 Ppm
The anomalous magnetic moment amu = ( g - 2)/2 of the negative muon has been measured to 0.7 ppm in an experiment at Brookhaven National Laboratory. Prior data runs at Brookhaven were taken with the positive muon, so this constitutes the first improved measurement of the negative muon's magnetic …

Measurement of the Anomalous Magnetic Moment of Tau Lepton with CMS Experiments and Improvements to the Zero Degree Calorimeters at CMS
… Electron-Positron Collider. Measurements of the anomalous magnetic moment of leptons have recently gained interest owing to the tension between experimental measurements of the anomalous magnetic moment of muons am at the Muon g-2 experiment [1] and Standard Model predictions [2]. If physics …

A measurement of the magnetic field systematic correction to the muon anomalous magnetic moment associated with muon phase space in experiment BNL E821
… of a continuing four year effort to measure the anomalous magnetic moment of the muon to 0.35 ppm has been completed. The measurement hopes to provide a direct experimental determination of the single loop weak renormalization with 23 percent resolution, and will place more stringent constraints …

Magnetic Field Determination for Run 1 of the Fermilab Muon g-2 Experiment
… $g-2$ experiment at Fermilab aims to measure the anomalous magnetic moment of the muon, $a_{\mu}$, to a precision of 140 parts per billion (ppb). The measurement will shed light on the current $>$3$\sigma$ deviation between Standard Model calculations and the previous measurement made at …

Exploration of nucleon structure in lattice QCD with chiral quarks
… nucleon charge, magnetization, and axial radii, anomalous magnetic moment, and axial charge. In addition, we compute quark contributions to the nucleon momentum and spin. Our calculation is novel for three reasons. It is a first full QCD calculation using both sea and valence chiral quarks with …

Beam Dynamics Challenges in the Muon g-2 Experiment
The muon's anomalous magnetic moment $a_{\mu}$ has hinted at physics beyond the standard model for nearly 20 years. The Muon $g-2$ experiment at Fermilab aims to measure $a_{\mu}$ to 140 parts per billion (ppb) precision. The 460 ppb result from its first data run (Run-1), released in 2021, agreed …

PHENOMENOLOGY OF THE STANDARD MODEL AND BEYOND
… precision observables (EWPOs) and the anomalous magnetic moment of the muon (g − 2), offer a complementary approach to direct searches by probing virtual effects of new physics. A crucial input to global EW fits is the top quark mass mt, which must be knownwith high precision to fully …

Measurement of Generalized GDH Integrand for the Neutron and 3He at Low Q2
… Gerasimov-Drell-Hearn (GDH) sum rule relates the anomalous magnetic moment to a weighted integral over the photo-absorption cross section. Its generalized form is extended for the virtual photon absorption at an arbitrary four momentum transfer square ($Q^2$) and thus provides a unique relation to …
