Query: Electroweak fermion triangle loop contributions to the muon anomalous
  magnetic moment revisited   The contribution to the muon anomalous magnetic moment from the fermion
triangle loop diagrams connected to the muon line by a photon and a $Z$ boson
is reanalyzed in the unitary gauge. With use of the anomalous axial-vector Ward
identity, it is shown that the calculation in the unitary gauge exactly
coincides with the one in the 't Hooft-Feynman gauge. The part which arises
from the ordinary axial-vector Ward identity corresponds to the contribution of
the neutral Goldstone boson. For the top-quark contribution, the one-parameter
integral form is obtained up to the order of $m_\mu^2/m_Z^2$. The results are
compared with those obtained by the asymptotic expansion method.
