“…This reflects the well-known fact that a longer running generates a sizeable A t for heavy enough gluinos, so that a lighter stop sector can provide the required radiative correction to the Higgs mass due to the stop LR mixing effects, see e.g. [40]. Secondly, we see that the fine-tuning prefers large M as well.…”

We study models of gauge-mediated supersymmetry breaking with messengers that do not belong to complete representations of grand-unified gauge groups. We show that certain setups characterized by heavy Wino can greatly improve the fine tuning with respect to models with unified messengers, such as minimal gauge mediation. The typical models with low tuning feature multi-TeV superparticles, with the exception of the Higgsinos and possibly Bino and right-handed sleptons. As a consequence, the absence of signals for supersymmetry at the LHC is trivially accommodated in our framework. On the other hand, testing these models will be challenging at the LHC. We finally show that the gravitino can be a consistent candidate for cold dark matter, provided a rather low reheating temperature, if a standard thermal history of the universe is assumed.

In general, we can propose the hybrid supersymmetry breakings and hybrid mediations in the Supersymmetric Standard Models (SSMs). In this paper, we study the hybrid mediation for supersymmetry (SUSY) breaking. In particular, we study how to keep the good properties of gravity mediation, gauge mediation, and anomaly mediation, while solve their problems simultaneously. As an example, we consider the gauge-gravity mediation, where all the supersymmetric particles (sparticles) obtain the SUSY breaking soft terms from the traditional gravity mediation while gauge mediation gives dominant contributions to the soft terms in the colored sector due to the splitted messengers. Thus, we can realize the electroweak supersymmetry naturally where the sleptons, sneutrinos, and electroweakinos are light within one TeV while the squarks and gluino are heavy around a few TeVs. And then we can explain 125 GeV Higgs mass, satisfy the LHC SUSY search bounds, and explain the anomalous magnetic momement of muon, etc. Moreover, the gluino and squarks are well beyond the current LHC Run II searches.

“…In this paper we focus on the collider phenomenology of the remaining part of the parameter space, where the stops are below 5 TeV. This part of parameter space is complementary to the more standard split-SUSY and heavy SUSY scenarios, and was somehow neglected in previous studies of the GGM phenomenology [57][58][59][60][61], essentially because it is difficult to study by taking different 2D slices in terms of the UV parameters. We estimate the current constraints and the reach of the high luminosity LHC (HL-LHC) by mapping the viable GGM parameter space into a set of representative simplified models and identify the most relevant simplified topologies.…”

We show that the predictivity of general gauge mediation (GGM) with TeVscale stops is greatly increased once the Higgs mass constraint is imposed. The most notable results are a strong lower bound on the mass of the gluino and right-handed squarks, and an upper bound on the Higgsino mass. If the µ-parameter is positive, the wino mass is also bounded from above. These constraints relax significantly for high messenger scales and as such long-lived NLSPs are favored in GGM. We identify a small set of most promising topologies for the neutralino/sneutrino NLSP scenarios and estimate the impact of the current bounds and the sensitivity of the high luminosity LHC. The stau, stop and sbottom NLSP scenarios can be robustly excluded at the high luminosity LHC.
