Query: Scalar Decay Constant and Yukawa Coupling in Walking Gauge Theories   We propose an approach for the calculation of the yukawa coupling through the
scalar decay constant and the chiral condensate in the context of the extended
technicolor (ETC). We perform the nonperturbative computation of the yukawa
coupling based on the improved ladder Schwinger-Dyson equation. It turns out
that the yukawa coupling can be larger or smaller than the standard model (SM)
value, depending on the number $N_D$ of the weak doublets for each technicolor
(TC) index. It is thus nontrivial whether or not the huge enhancement of the
production of the scalar via the gluon fusion takes place even for a walking TC
model with a colored techni-fermion. For the typical one-family TC model near
conformality, it is found that the yukawa coupling is slightly larger than the
SM one, where the expected mass of the scalar bound state is around 500 GeV. In
this case, the production cross section via the gluon fusion is considerably
enhanced, as naively expected, and hence such a scalar can be
discovered/excluded at the early stage of the LHC.
