Abstract
Contributions to the muon anomalous magnetic moment are evaluated in the
technicolor model with scalars and topcolor assisted technicolor model. In the
technicolor model with scalars, the additional contributions come from the
loops of scalars, which were found sizable only for a very large \$f/f^'\$
disfavored by the experiment of \$bs\gamma\$. The topcolor effect is also
found to be large only for an unnaturally large \$\tanþeta'\$, and thus the
previously evaluated loop effects of extended technicolor bosons, suppressed by
\$m\_\mu^2/M\_ETC^2\$, must be resorted to account for the E821 experiment. So,
if the E821 experiment result persists, it would be a challenge to technicolor
models.
