ANTISYMMETRIC TENSOR FIELD COUPLED TO CHIRAL MATTER AND DYNAMIC SYMMETRY-BREAKING

The minimal coupling of chiral fermions to a second rank antisymmetric tensor field is considered, and an alternative to the standard model is discussed in which the Higgs doublet is replaced by a real scalar a nd a second rank antisymmetric tensor. The dynamical breaking of elect roweak symmetry, via the Nambu-Jona-Lasinio mechanism, is shown to occ ur due to natural four-Fermi interactions. The mean field theory due t o instanton configurations in the antisymmetric tensor field is also p resented and possible cosmological applications of this model are disc ussed.
