  We present a lattice Monte Carlo simulation for the evaluation of the
spectrum of a confining Yang-Mills theory without Goldstone boson. We show that
this theory is a very good candidate for describing composite weak bosons. In
order to perform the spectrum analysis we have used standard lattice QCD Monte
Carlo methods. We have also developed an efficient method to evaluate the mass
of the pseudoscalar isosinglet which is present in our theory.
