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. Our 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 with the mechanism of QCD. Our results go beyond the strong coupling results of Schlereth, extending the analysis away from the infinitely strong coupling limit. This is an important analytic support to our intensive lattice Monte Carlo simulation of the spectrum of this theory. © 1995 The American Physical Society.
