Abstract

It is proposed that a dynamical mass for a fourth family of quarks is responsible for breaking of the weak interactions, and for breaking of the extended technicolor interactions which provide mass to the third family. This greatly simplifies the extended technicolor sector and avoids fermions with exotic quantum numbers. A technicolor sector is still required but it is lighter than usual. The most attractive-channel hypothesis for symmetry breakdown is relied on.
