A GENERAL HIGGS SECTOR - CONSTRAINTS AND PHENOMENOLOGY

We have investigated some phenomenological aspects of an SU(2) x U(1) scenario where scalars belonging to arbitrary representations of SU(2) are involved in electroweak symmetry breaking. The resulting interact ion terms are derived. Some constraints are obtained on the arbitrary scalar sector from the requirement of tree-level unitarity in longitud inal gauge boson scattering. We also show that there is a remarkable c omplimentarity between the constraints on a general structure from the rho parameter and those from precision measurement of the Zb (b) over bar; vertex. Finally, some salient features about the production of s uch Higgs bosons in e(+)e(-) collision are discussed.
