Loop suppressed electroweak symmetry breaking and naturally heavy superpartners

TL;DR

This paper proposes a supersymmetric model where heavy stop masses originate from mixing with vectorlike partners, reducing their impact on the Higgs mass and predicting new heavy fermion and scalar top partners.

Contribution

It introduces a novel mechanism for heavy stop masses via mixing with vectorlike partners, avoiding large negative Higgs mass squared contributions.

Findings

Heavy stop masses (~10 TeV) do not destabilize the Higgs mass.

The model predicts new fermion and scalar partners at the TeV scale.

Threshold corrections are the main contribution to the Higgs mass squared.

Abstract

A model is presented in which O(10 TeV) stop masses, typically required by the Higgs boson mass in supersymmetric models, do not originate from soft supersymmetry breaking terms that would drive the Higgs mass squared parameter to large negative values but rather from the mixing with vectorlike partners. Their contribution to the Higgs mass squared parameter is reduced to threshold corrections and, thus, it is one loop suppressed compared to usual scenarios. New fermion and scalar partners of the top quark with O(10 TeV) masses are predicted.
