ANOMALOUS WEAK BOSON COUPLINGS - SUGGESTIONS FROM UNITARITY AND DYNAMICS

Taking into account the constraints from LEP1 and lower energy experim ents, we identify the seven SU(2) x U(1) gauge invariant purely bosoni c dim = 6 operators which provide a quite general description of how N ew Physics could reflect in the bosonic world, if it happens that all new degrees of freedom are too heavy to be directly produced in the fu ture colliders. Five of these operators are CP conserving and the rema ining ones are CP violating. We derive the unitarity constraints for t he CP violating operators and compare them with the already known cons traints for the CP conserving ones. Dynamical renormalizable models ar e also presented, which partly elucidate what the appearance of each o f these operators can teach us on the mechanism of spontaneous gauge s ymmetry breaking.
