“…Such a state could have the quantum numbers of a Higgs field and mix with the MSSM Higgs fields to participate in electroweak symmetry breaking [73][74][75][76]. If this occurs, our results on the metastability of the MSSM may no longer apply.…”

In the Minimal Supersymmetric Standard Model (MSSM), a Higgs boson mass of 125 GeV can be obtained with moderately heavy scalar top superpartners provided they are highly mixed. The source of this mixing, a soft trilinear stop-stop-Higgs coupling, can result in the appearance of charge-and color-breaking minima in the scalar potential of the theory. If such a vacuum exists and is energetically favorable, the Standard Model-like vacuum can decay to it via quantum tunnelling. In this work we investigate the conditions under which such exotic vacua arise, and we compute the tunnelling rates to them. Our results provide new constraints on the scalar top quarks of the MSSM.

“…Furthermore, unlike the MSSM, the modified potential has no flat directions that may cause an instability. * In [20] a heavier Higgs mass was claimed possible if a stop bound state condenses due to a strong trilinear coupling. In [21] a new moderately strong gauge interaction was used to enhance the Higgs quartic coupling, assuming a large supersymmetry breaking of about 7 TeV in a part of the theory.…”

Minimal supersymmetric fat Higgs model

et al. 2004

We present a calculable supersymmetric theory of a composite "fat" Higgs boson. Electroweak symmetry is broken dynamically through a new gauge interaction that becomes strong at an intermediate scale. The Higgs mass can easily be 200-450 GeV along with the superpartner masses, solving the supersymmetric little hierarchy problem. We explicitly verify that the model is consistent with precision electroweak data without fine-tuning. Gauge coupling unification can be maintained despite the inherently strong dynamics involved in electroweak symmetry breaking. Supersymmetrizing the Standard Model therefore does not imply a light Higgs mass, contrary to the lore in the literature. The Higgs sector of the minimal Fat Higgs model has a mass spectrum that is distinctly different from the Minimal Supersymmetric Standard Model.

“…Let us briefly review the strongly coupled phase of the MSSM [1][2][3]. Supersymmetry breaking introduces the following trilinear terms in the Lagrangian: and a similar term in the down sector.…”

“…However, the lack of direct experimental evidence for superpartners, as well as the recent discovery of a Higgs boson with a mass that is heavier than one would naively expect in the MSSM, challenges the viability of low-energy supersymmetry in its simplest realizations. At the same time, there exists a possibility for a strongly coupled form of MSSM, which is associated with a large value of the trilinear supersymmetry breaking coupling [1][2][3]. In this strongly coupled regime, the squarks form bound states via the exchange of Higgs bosons, creating some additional composite states, which can have some non-zero vacuum expectation values (VEVs).…”

Phenomenology of supersymmetric models with a symmetry-breaking seesaw mechanism

We explore phenomenological implications of the minimal supersymmetric standard model (MSSM) with a strong supersymmetry breaking trilinear term. Supersymmetry breaking can trigger electroweak symmetry breaking via a symmetry-breaking seesaw mechanism, which can lead to a low-energy theory with multiple composite Higgs bosons. In this model, the electroweak phase transition can be first-order for some generic values of parameters. Furthermore, there are additional sources of CP violation in the Higgs sector. This opens the possibility of electroweak baryogenesis in the strongly coupled MSSM. The extended Higgs dynamics can be discovered at Large Hadron Collider or at a future linear collider.
