Light Stops, Heavy Higgs, and Heavy Gluinos in Supersymmetric Standard Models with Extra Matters

TL;DR

This paper investigates supersymmetric models with extra matter fields, demonstrating that heavy gluinos and light stops can coexist with a Higgs boson consistent with observations, depending on the soft mass hierarchy and gaugino mass assumptions.

Contribution

It introduces scenarios with heavy gluinos and light stops in SUSY models with extra vector-like matter, showing how the observed Higgs mass and specific LSP candidates can be achieved.

Findings

Light stop and Higgs boson can be realized with hierarchical soft masses.

Neutralino LSP is possible with non-universal gaugino masses.

Heavy gluinos and light stops coexist in certain parameter spaces.

Abstract

We have explored the possibilities of scenarios with heavy gluinos and light stops in supersymmetric (SUSY) standard models with extra vector-like multiplets. If we assume the hierarchical structure for soft masses of the minimal supersymmetric standard model (MSSM) scalar fields and extra scalars, the light stop and the observed Higgs boson can be realized. While the stau is the lightest SUSY particle (LSP) in broad parameter space, we have found that the neutralino LSP is realized in the case that the non-zero soft parameters for the MSSM Higgs doublets or the non-universal gaugino masses are assumed.
