Abstract
We show that the vector boson, introduced to explain the anomalous decay, could play a role in the muon’s (electron’s) anomalous magnetic moment and the muonic Lamb shift anomaly. We compute an upper bound on the couplings of to leptons and nucleons, analyzing these anomalies. We further constrain the possible kinetic mixing with the boson of the Standard Model by using the latest available data on the boson mass.
