The standard model of particle physics describes the vast majority of experiments and observations involving elementary particles. Any deviation from its predictions would be a sign of new, fundamental physics. One long-standing discrepancy concerns the anomalous magnetic moment of the muon, a measure of the magnetic field surrounding that particle. Standard-model predictions1 exhibit disagreement with measurements2 that is tightly scattered around 3.7 standard deviations. Today, theoretical… 

Towards an Independent Determination of Muon g-2 from Muonium Spectroscopy.

TLDR
It is shown that muonium spectroscopy in the coming years can reach a precision high enough to determine the anomalous magnetic moment of the muon below one part per million (ppm), and the good agreement between theory and experiment for the electron g-2 indicates that new physics interactions are unlikely to affectMuonium Spectroscopy down to the envisaged precision.

Custodial symmetry for muon g−2

We discuss the recent results on the muon anomalous magnetic moment in the context of new physics models with light scalars. We propose a model in which the one-loop contributions to g− 2 of a scalar

Impact of correlations between $a_\mu$ and $\alpha_{QED}$ on the EW fit.

We study the potential impact on the electroweak (EW) fits due to the tensions between the current determinations of the hadronic vacuum polarisation (HVP) contributions to the anomalous magnetic

Supersymmetric interpretation of the muon g – 2 anomaly

Fake doublet solution to the muon anomalous magnetic moment

Standard Model extensions that use strictly off-shell degrees of freedom – the fakeons – allow for new measurable interactions at energy scales usually precluded by the constraints that target the

Mixed modulus and anomaly mediation in light of the muon g − 2 anomaly

Abstract The new measurement of the anomalous magnetic moment of muon at the Fermilab Muon g− 2 experiment has strengthened the significance of the discrepancy between the standard model prediction
