Muon anomaly and non-locality
arXiv:2206.06037 · doi:10.1016/j.physletb.2022.137128
Abstract
We show that the discrepancy between the observed value of the muon anomalous moment and the standard model prediction can be explained in the framework of nonlocal theories. We compute the leading order and next to leading order nonlocal correction to the anomalous magnetic moment and we find that it depends on the nonlocality scale and the fermion mass as . Such a dependence of the anomalous magnetic momentum allows to explain, in a flavor-blind nonlocality scale, why the observed anomalous magnetic moment of the electron is much closer to the standard model prediction, and permits to predict a large anomaly that should exist for the particle. We also determine the lower bounds on the nonlocality scale, for both flavor-blind and flavor-dependent scenarios.
