Type 1 2HDM as effective theory of supersymmetry

TL;DR

This paper proposes that the Type 1 two Higgs doublet model can serve as an effective theory for supersymmetry under specific high-scale breaking and gauge mediation conditions, resulting in a Higgs mass consistent with observations.

Contribution

It demonstrates that the Type 1 2HDM can be derived as an effective theory of supersymmetry, contrasting with the traditional Type 2 model, especially in high-scale scenarios.

Findings

Higgs boson mass can be 125 GeV in this model

Type 1 2HDM can emerge from supersymmetry with high-scale breaking

Distinct Higgs spectrum compared to ordinary models

Abstract

It is generally believed that the low energy effective theory of the minimal supersymmetric standard model is the type 2 two Higgs doublet model. We will show that the type 1 two Higgs doublet model can also as the effective of supersymmetry in a specific case with high scale supersymmetry breaking and gauge mediation. If the other electroweak doublet obtain the vacuum expectation value after the electroweak symmetry breaking, the Higgs spectrum is quite different. A remarkable feature is that the physical Higgs boson mass can 125 GeV unlike in the ordinary models with high scale supersymmetry in which the Higgs mass is generally around 140 GeV.
