Most of the Higgs efforts of the CDF and D0 collaborations are centered on finding a Standard Model Higgs boson. However the Standard Model is incomplete and there are proposed extensions to the Standard Model, many of which feature one or more Higgs bosons as well. These are often similar to the Standard Model Higgs, but differ in their couplings to other particles. For the purposes of this pr...

We show that it is possible to construct models in which the width of the Higgs boson is arbitrary either smaller or larger than a standard model Higgs boson of the same mass. There are no new fields into which the Higgs boson decays. Instead, the coupling of the Higgs boson to the gauge bosons is adjusted. We construct and analyze weakly–coupled models with arbitrary–width Higgs bosons to inve...

This paper is motivated by three issues associated with the supersymmetric extension of the standard model: the μ problem, the possibility of raising the upper bound on the lightest-Higgs-boson mass, and the triviality problem associated with the Higgs sector. A new scheme based on the Higgs-Higgs condensation at low energy is proposed, and it is shown that these three issues are well solved by...

Searches for Higgs bosons at LEP are summarized. No Higgs boson has been observed yet. For the Standard model Higgs boson, the lower bound on the mass is 113:3 GeV=c. In the Minimal Supersymmetric Standard Model, for representative scans of the SUSY parameters, the limits on the CPeven and the CP-odd neutral Higgs bosons masses are both 90:5 GeV=c. For the charged Higgs bosons predicted by two-...

We derive a sum rule which shows how to extend LEP limits on the masses of the lightest CP-even and CP-odd Higgs bosons of a CP-conserving two-Higgs-doublet model to any two Higgs bosons of a general CP-violating two-Higgs-doublet model. We generalize the analysis to a Higgs sector consisting of an arbitrary number of Higgs doublets and singlets, giving explicit limits for the CP-conserving and...

Tevatron is currently the only place where we can search for not only the standard model (SM) Higgs boson but also non-SM Higgs bosons. CDF and DØ have started searching for the exotic Higgs bosons including supersymmetric Higgs bosons and doubly charged Higgs bosons. DØ recently updated the results of the minimal supersymmetric standard model (MSSM) Higgs boson search using hbb̄ → bb̄bb̄ final st...

Non-minimal Higgs sectors occur in the Standard Model with more than one Higgs doublet, as well as in theories that go beyond the Standard Model. In this report, we discuss how Higgs search strategies must be altered, with respect to the Standard Model approaches, in order to probe the non-minimal Higgs sectors at the SSC.
