TL;DR
This paper proposes a novel perspective on supersymmetry, linking maximal stop mixing to UV boundary conditions, and suggests that a pseudo-Goldstone Higgs with extra fermions can address fine-tuning and Higgs decay issues.
Contribution
It introduces a new approach to SUSY model building, connecting stop mixing with UV boundary conditions and incorporating vector-like fermions for Higgs phenomenology.
Findings
Maximal stop mixing correlates with tachyonic stops at UV boundary.
Pseudo-Goldstone Higgs can be light without severe fine-tuning.
Extra vector-like fermions explain Higgs to di-photon rates.
Abstract
New SUSY thought is presented. Maximal stop mixing needed for 125 GeV Higgs is linked to the tachyonic stop at the UV boundary. Large does not mean the severe fine tuning if Higgs comes out as a pseudo-Goldstone boson. The small mass of the pseudo-Goldstone Higgs is overcome with extra vector-like fermions needed to explain the Higgs to di-photon rates.
