“…Indeed, the threshold corrections involving electroweak gauginos are now at the weak scale, and could potentially be determined by measuring the electroweak gaugino masses and couplings. Motivated by Split Supersymmetry, several groups have investigated supersymmetry breaking at a high scale, including models with supersymmetry breaking at a Peccei-Quinn breaking scale of 10 11 GeV [29] and models with gauge coupling unification at 10 16-17 GeV via non-SU(5) hypercharge normalization [30][31][32]. In these models, a supersymmetric boundary condition on the quartic coupling yields a Higgs mass prediction and, for large values of tan β and taking account different values of the top quark mass, these predictions are not far from our central value of 141 GeV.…”

If supersymmetry is broken directly to the Standard Model at energies not very far from the unified scale, the Higgs boson mass lies in the range (128 -141) GeV. The end points of this range are tightly determined. Theories with the Higgs boson dominantly in a single supermultiplet predict a mass at the upper edge, (141 ± 2) GeV, with the uncertainty dominated by the experimental errors on the top quark mass and the QCD coupling. This edge prediction is remarkably insensitive to the supersymmetry breaking scale and to supersymmetric threshold corrections so that, in a wide class of theories, the theoretical uncertainties are at the level of ±0.4 GeV. A reduction in the uncertainties from the top quark mass and QCD coupling to the level of ±0.3 GeV may be possible at future colliders, increasing the accuracy of the confrontation with theory from 1.4% to 0.4%. Verification of this prediction would provide strong evidence for supersymmetry, broken at a very high scale of ≈ 10 14±2 GeV, and also for a Higgs boson that is elementary up to this high scale, implying fine-tuning of the Higgs mass parameter by ≈ 20 -28 orders of magnitude. Currently, the only known explanation for such fine-tuning is the multiverse.

“…Therefore, in order to render the Z R 4 symmetry anomaly-free, the presence of further SM-charged is required. 15 For this reason, 15 By contrast, solely within the IYIT sector, the Z R we have assumed the existence of k new quark/antiquark pairs Q i ,Q i ∼ (5, 5 * ) in this paper, which obtain masses of the order of the gravitino mass from coupling to the SUSY-breaking sector.…”

Peccei-Quinn symmetry from dynamical supersymmetry breaking

et al. 2015

The proximity of the Peccei-Quinn scale to the scale of supersymmetry breaking in models of pure gravity mediation hints at a common dynamical origin of these two scales. To demonstrate how to make such a connection manifest, we embed the Peccei-Quinn mechanism into the vector-like model of dynamical supersymmetry breakingà la IYIT. Here, we rely on the anomaly-free discrete Z R 4 symmetry required in models of pure gravity mediation to solve the µ problem to protect the Peccei-Quinn symmetry from the dangerous effect of higher-dimensional operators. This results in a rich phenomenology featuring a QCD axion with a decay constant of O 10 10 GeV and mixed WIMP/axion dark matter. In addition, exactly five pairs of extra 5 and 5 * matter multiplets, directly coupled to the supersymmetry breaking sector and with masses close to the gravitino mass, m 3/2 ∼ 100 TeV, are needed to cancel the Z R 4 anomalies.

“…We denote the gauge couplings for U(1) Y , SU(2) L , and SU(3) C as g Y , g 2 , and g 3 , respectively, and define g 1 ≡ 5/3g Y . The major prediction in the models with high-scale supersymmetry breaking is the Higgs boson mass [7,19,29]. We can calculate the Higgs boson quartic coupling λ at the supersymmetry breaking scale…”

We systematically construct two kinds of models with canonical gauge coupling unification and universal high-scale supersymmetry breaking. In the first we introduce standard vector-like particles while in the second we also include non-standard vector-like particles. We require that the gauge coupling unification scale is from 5 × 10 15 GeV to the Planck scale, that the universal supersymmetry breaking scale is from 10 TeV to the unification scale, and that the masses of the vector-like particles (M V ) are universal and in the range from 200 GeV to 1 TeV. Using two-loop renormalization group equation (RGE) running for the gauge couplings and one-loop RGE running for Yukawa couplings and the Higgs quartic coupling, we calculate the supersymmetry breaking scales, the gauge coupling unification scales, and the corresponding Higgs mass ranges. When the vector-like particle masses are less than 1 TeV, these models can be tested at the LHC.
