Computation of the Peskin-Takeuchi S parameter in a

model of dynamical electroweak symmetry breaking

ABSTRACT

We study a model of dynamical electroweak symmetry breaking using its dual gravitational

description. We compute the masses and decay constants of the vector and

axial vector particles . We note that the value of the Peskin-Takeuchi S parameter

could accurately be estimated using the dominance of the low lying vector mesons.
