First observation of electroweak photon plus two jets production yields a cross section of 202 fb consistent with the standard model prediction of 177 fb at greater than 5 sigma significance.
The paper reviews collider-based measurements of the tau anomalous magnetic moment, highlighting LHC ultra-peripheral collisions and projected sensitivities at future facilities like Belle II and FCC.
