Composite Weak Bosons in a Confining Gauge Theory without Goldstone   Bosons: a Strong Coupling Expansion Analysis
  We consider a confining Yang-Mills theory without Goldstone Bosons which could describe the bosonic sector of the weak interactions. This model can be gauge invariantly regularized on a lattice. A strong coupling analysis of the low lying bound state spectrum indicates that the vector isotriplet bound state (the right quantum number to represent the W-boson) could be the lightest state if the mass of the pseudoscalar isosinglet is raised sufficiently by the effect of the chiral anomaly (in analogy to the $\eta'$ mechanism of QCD). This work is a preliminary study in support to an intensive lattice Monte Carlo analysis of the model.
