چکیده

We describe the properties of Higgs bosons in a class of supersymmetric theories. We consider models in which the low-energy sector contains two weak complex doublets and perhaps one complex gauge-singlet Higgs field. Supersymmetry is assumed to be either softly or spontaneously broken, thereby imposing a number of restrictions on the Higgs boson parameters. We elucidate the Higgs boson masses and present Feynman rules for their couplings to the gauge bosons, fermions and scalars of the theory. We also present Feynman rules for vertices which are related by supersymrnetry to the above couplings. Exact analytic expressions are given in two useful limits one corresponding to the absence of the gauge-singlet Higgs field and the other corresponding to the absence of a supersymmetric Higgs mass term.

Phenomenology of light Higgs bosons in supersymmetric left-right models

We carry out a detailed analysis of the light Higgs bosons in supersymmetric leftright models (SLRM). This includes models with minimal particle content and those with additional Higgs superfields. We also consider models with non-renormalizable higher-dimensional terms. We obtain an upper bound on the mass of the lightest CP -even neutral Higgs boson in these models. The upper bound depends on...

Searches for “Other” Higgs Bosons at LEP

Recent LEP searches for Higgs bosons in models other than the Minimal Standard Model and the Minimal Supersymmetric Standard Model are reviewed. Limits are presented for Higgs bosons decaying into diphotons or invisible particles, and for charged Higgs bosons.

Zu–th 5/98 Pm–98/1 Lower Bounds on Charged Higgs Bosons from Lep and Tevatron

We point out that charged Higgs bosons can decay into final states different than τντ and cs̄, even when they are light enough to be produced at LEP or at the Tevatron, through a t–quark decay. These additional decay modes are overlooked in ongoing searches and alter existing lower bounds on the mass of charged Higgs bosons present in supersymmetric and two Higgs doublets models. The discovery o...

We point out that charged Higgs bosons can decay into final states different from τντ and cs̄, even when they are light enough to be produced at LEP II or at the Tevatron through top quark decays. These additional decay modes are overlooked in ongoing searches even though they alter the existing lower bounds on the mass of the charged Higgs bosons that are present in supersymmetric and two Higgs...

Higgs Decays into Leptons *

We discuss the prospects for the discovery of neutral Higgs bosons (φ 0 = H 0 , h 0 , A 0) in multi-Higgs doublet models via their decays into leptons at hadron colliders. A major focus will be searching for Higgs bosons produced with bottom quarks via Higgs decays into muon pairs (pp → b ¯ bφ 0 → b ¯ bµ¯ µ + X) at the CERN Large Hadron Collider within the framework of the minimal supersymmetri...
