“…Note also that the particular spectrum in Eq. ( 1) 1 was achieved in the context of Yukawa-gauge mediation [40] and semi-direct gauge mediation with chiral messengers [41,42]. In the former model, the gaugino and sfermion masses may arise at two and three loops respectively.…”

Abstract:We propose a simple model of split supersymmetry from gauge mediation. This model features gauginos that are parametrically a loop factor lighter than scalars, accommodates a Higgs boson mass of 125 GeV, and incorporates a simple solution to the µ − b µ problem. The gaugino mass suppression can be understood as resulting from collective symmetry breaking. Imposing collider bounds on µ and requiring viable electroweak symmetry breaking implies small a-terms and small tan β -the stop mass ranges from 10 5 to 10 8 GeV. In contrast with models with anomaly + gravity mediation (which also predict a one-loop loop suppression for gaugino masses), our gauge mediated scenario predicts aligned squark masses and a gravitino LSP. Gluinos, electroweakinos and Higgsinos can be accessible at the LHC and/or future colliders for a wide region of the allowed parameter space.

“…The formalism of general gauge mediation [3][4][5][6] encodes the effects of supersymmetry breaking in a set of current correlators. It assumes that when a set of parameters ({α i }, {λ j }) → 0, the supersymmetric standard model and the sector that breaks supersymmetry utterly decouple from each other.…”

Abstract:We extend the framework of general gauge mediation to cases where the mediating fields have a nontrivial spectral function, as might arise from strong dynamics. Demonstrating through examples, this setup describes a broad class of possible models of gauge mediated supersymmetry breaking. A main emphasis is to give general formulas for cross sections for σ(visible → hidden) in these resonance models. We will also give formulas for soft masses, A-terms and demonstrate the framework with a holographic setup.

Heavy standard model-like Higgs boson and a light stop from Yukawa-deflected gauge mediation

To obtain a SM-like Higgs boson around 125 GeV in the Minimal Supersymmetric Standard Model with minimal gauge mediation of supersymmetry breaking (GMSB), a heavy stop at multiTeV level is needed and incurs severe fine-tuning, which can be ameliorated in the framework of the deformed GMSB with visible-hidden direct Yukawa interactions (YGMSB). We examine some general features of the YGMSB and focus on the scenario with Higgs-messenger couplings (H−YGMSB) which can automatically maintain the minimal flavor violation (MFV). It turns out that such a Yukawa mediation scenario can give a large −A t and −m 2 t L,R , leading to a maximal stop mixing, and thus can readily give a light stop (t 1 ) below the TeV scale. However, we find that in the minimal H−YGMSB scenario, m 2 Hu is too large and then the electroweak symmetry breaking is inconsistent with the large stop mixing. To solve this problem, we modify the hidden sectors in two ways, adding a new strong gauge dynamics or introducing the (10, 10) messengers.For each case we present some numerical study.
