Abstract
We review the phenomenology of electroweak theories based on composite leptons and quarks. In particular, we concentrate on a concept of compositeness, in which the short range weak interaction between leptons and quarks is treated in close analogy to the short range strong interaction between hadrons. The standard neutral current structure as well as the standard boson mass relations appear as dynamical low energy approximations based on W- dominance without invoking SU(2)I x U(l)Y symmetry at short distances.

The conjecture that the short range weak interaction shows features, which are analogous to hadron interactions, e.g., a full spectrum of weak bosons as mediators of the weak interactions, has been advocated by:

The prediction9 of the canonical mass relations from compositeness and W-dominance has been at variance with the conjecture of some of the authors of Ref. 11 that compositeness implies W-boson masses of at least 120 GeV.
The forward-backward asymmetry expected for W-production still needs empirical confirmation.
