Natural SUSY from unification of SUSY breaking and GUT breaking
Yuji Omura
TL;DR
This paper presents a supersymmetric unification model where GUT breaking and SUSY breaking originate from the same field, naturally generating soft terms and achieving realistic electroweak symmetry breaking with relatively light stops.
Contribution
It introduces a novel model linking GUT and SUSY breaking via a single field, producing realistic Higgs mass and electroweak symmetry breaking.
Findings
Nonzero A-term and B-term generated at one-loop
Electroweak symmetry breaking achieved with ~1 TeV stop mass
Predicts SM-charged particles from the symmetry breaking sector
Abstract
We introduce an explicit supersymmetric unification model where grand unified gauge symmetry breaking and supersymmetry (SUSY) breaking are caused by the same field. Besides, the SM-charged particles are also predicted by the symmetry breaking sector, and their loop corrections induce the soft SUSY breaking terms. Especially, nonzero A-term and B-term are generated at one-loop level according to the mediation via the vector superfields, so that the electro-weak symmetry breaking and 125 GeV Higgs mass could be achieved even if the stop mass is around 1 TeV.
