PHENOMENOLOGY OF A NONSTANDARD HIGGS-BOSON IN WLWL SCATTERING

In this paper we consider the phenomenology of a nonstandard Higgs bos on in longitudinal gauge boson scattering. First, we present a composi te Higgs model [based on an SU(4)/Sp(4) chiral-symmetry breaking patte rn] in which there is a nonstandard Higgs boson. Then we explore, in a model-independent way, the phenomenology of such a nonstandard Higgs boson by calculating the leading one-loop logarithmic corrections to l ongitudinal gauge boson scattering. This calculation is done using the equivalence theorem and the Higgs boson is treated as a scalar-isosca lar resonance coupled to the Goldstone bosons of the SU(2)(L)xSU(2)(R) /SU(2)V chiral symmetry breaking. We show that the most important devi ation:om the one-Higgs-doublet standard model is parametrized by one u nknown coefficient which is related to the Higgs-boson width. The impl ications for future hadron colliders are discussed.
