Abstract
In the framework of the electroweak chiral Lagrangian, the one-loop induced effects of the anomalous coupling, which includes both left- and right-handed complex components, on the static electromagnetic properties of the boson and the quark are studied. The attention is focused mainly on the -violating electromagnetic properties. It is found that the anomalous coupling can induce both -violating moments of the boson, namely, its electric dipole () and magnetic quadrupole () moments. As far as the quark is concerned, a potentially large electric dipole moment () can arise due to the anomalous coupling. The most recent bounds on the coupling left- and right-handed parameters from meson physics lead to the following estimates and , which are 7 and 14 orders of magnitude larger than the standard model (SM) predictions, whereas may be as large as , which is about 8 orders of magnitude larger than its SM counterpart.
