Final-State Interaction of Longitudinal Vector Bosons

Abstract

In the standard Higgs model of electroweak symmetry breaking, the Higgs boson is associated with both vector-boson and fermion mass generation. In contrast, we discuss a two-Higgs-doublet model in which these masses are associated with two different scalar bosons. We show that the Higgs boson associated with vector-boson mass generation produces a {\it dip\/} in the cross section for $t\bar{t}\to ZZ$ via a final-state interaction. Such a dip will be difficult to observe at the LHC/SSC.
