Raising the Higgs Mass in Supersymmetric Models

TL;DR

This paper proposes two mechanisms to increase the Higgs boson mass at tree level in supersymmetric models, addressing experimental constraints without requiring very heavy superpartners, thus reducing fine-tuning issues.

Contribution

It introduces two novel tree-level mechanisms to raise the Higgs mass in supersymmetric models, expanding viable parameter space.

Findings

Two mechanisms successfully increase Higgs mass at tree level.

Reduced need for heavy superpartners to match experimental bounds.

Potentially less fine-tuning in supersymmetric models.

Abstract

The minimal supersymmetric standard model, and extensions, predicts a relatively light higgs particle if one supposes perturbativity until high scales. That fact is in conflict with nowadays data coming from LEPII fruitless searches for the Higgs boson. This bound is sufficient to rule out a big portion of the parameter space of the MSSM. In this letter we propose two mechanism of raising the higgs mass at tree level, thus not needing very heavy sparticles that would reintroduce some fine-tuning in the problem.
