  • Abstract We describe a color embedding, SU(3) c →SU(3) 1 ×SU(3) 2 , that is designed to break electroweak symmetries through top quark condensation. The minimal scheme of Bardeen, Hill and Lindner can be recovered by taking the scale of embedding large and fine-tunning the ratio of coupling constants. Models of this kind allow computation of the strength of higher dimension operators which are found to be small. Perhaps fine-tunning can ultimately be avoided in this scheme.
