Neutral triple gauge couplings (nTGCs) are absent in the Standard Model (SM) and at the dimension-6 level in the Standard Model Effective Field Theory (SMEFT), arising first from dimension-8 operators. As such, they provide a unique window for probing new physics beyond the SM. These dimension-8...
Recently there have been stronger and stonger disagreements between direct measurements of the anomalous magnetic moment of the muon and the standard-model prediction. Such a large discrepancy should signal the discovery of interactions or particles not present in the standard model. However, two independent determinations of the most uncertain contribution to the standard-model prediction...
