In the framework of the electroweak chiral Lagrangian, the one-loop induced
effects of the anomalous tbW coupling, which includes both left- and
right-handed complex components, on the static electromagnetic properties of
the W boson and the t quark are studied. The attention is focused mainly on
the CP-violating electromagnetic properties. It is found that the tbW
anomalous coupling can induce both CP-violating moments of the W boson,
namely, its electric dipole (μ~W) and magnetic quadrupole
(Q~W) moments. As far as the t quark is concerned, a potentially
large electric dipole moment (dt) can arise due to the anomalous tbW
coupling. The most recent bounds on the left- and right-handed parameters from
B meson physics lead to the following estimates μ~W10−23−10−22 e-cm and Q~W10−38−10−37 e-cm2, which
are 7 and 14 orders of magnitude larger than the standard model (SM)
predictions, whereas dt may be as large as 10−22 e-cm, which is about 8
orders of magnitude larger than its SM counterpart.Comment: This paper has been merged with hep-ph/0612171 for publication in
