The lightest neutral and doubly charged Higgs bosons of supersymmetric left-right models

TL;DR

This paper reviews the phenomenology of light Higgs bosons in supersymmetric left-right models, highlighting their properties, bounds, and potential experimental signatures, especially focusing on doubly charged Higgs bosons.

Contribution

It provides a comprehensive analysis of light Higgs scalars in various supersymmetric left-right models, including those with extended particle content and higher-dimensional terms.

Findings

Upper bound on the lightest CP-even neutral Higgs is larger than in MSSM.

Higgs couplings to fermions resemble those of the Standard Model.

Light doubly charged Higgs bosons could serve as distinctive experimental signatures.

Abstract

We review the phenomenology of light Higgs scalars in supersymmetric left-right models. We consider models with minimal particle content (with and without non-renormalizable higher-dimensional terms) and with additional Higgs superfields. The upper bound on the lightest CP-even neutral Higgs boson in these models is larger than in the minimal supersymmetric standard model, and the Higgs couplings to fermions approach those of the Standard Model. Possibly light doubly charged Higgs boson may provide the best signature of these models.
