The Phenomenology of a Non-Standard Higgs Boson IN $W_L{W}_L$ Scattering

Abstract

In this paper we consider the phenomenology of a ``non-standard'' Higgs Boson in longitudinal gauge-Boson scattering. First, we present a composite Higgs model (based on an $SU(4)/Sp(4)$ chiral-symmetry breaking pattern) in which there is a non-standard Higgs Boson. Then we explore, in a model-independent way, the phenomenology of such a non-standard Higgs by calculating the chiral logarithmic corrections to longitudinal gauge scattering. This calculation is done using the Equivalence theorem and the Higgs is treated as a scalar-isoscalar resonance coupled to the Goldstone Bosons of the \mbox{$SU(2{)}_L\times SU(2{)}_R/SU(2{)}_V$} chiral symmetry breaking. We show that the most important deviation from the one Higgs-doublet standard model is parameterized by one unknown coefficient which is related to the Higgs width. The implications for future hadron colliders are discussed.
