“…If the Z NR charge of S is 2α, the NMSSM is able to have the Z 4R or Z 20R symmetry. In the NMSSM with the GMSB, as is known well, some extra fields are necessary to couple with the singlet S in order to obtain a viable spectrum [18,19,20]. It is very interesting that we have already introduced such extra fields as the extra matter multiplets Ψ andΨ in order to cancel the anomalies of the Z 4R and Z 20R symmetries.…”

A discrete R-symmetry often appears as an exact gauge symmetry in the low energy effective theory of superstring theories. We search for such discrete Rsymmetries from a phenomenological point of view and find that Z 9R and Z 18R are candidates of the nonanomalous R-symmetry in the case of the minimal supersymmetric standard model. We also find Z 4R and Z 20R in the case that quarks and leptons are embedded in the SU(5) GUT multiplets. Interesting is that in the latter case all the solutions predict some extra matter multiplets and we find that the simplest choice of the extra matters is to take a pair of 5 and 5 * of SU(5) GUT whose mass is of order the SUSY breaking scale ∼ 1 TeV. We emphasize that the presence of such extra matters is testable in future hadron collider experiments.

Recent LHC data, together with the electroweak naturalness argument, suggest that the top squarks may be significantly lighter than the other sfermions. We present supersymmetric models in which such a split spectrum is obtained through "geometries": being "close to" electroweak symmetry breaking implies being "away from" supersymmetry breaking, and vice versa. In particular, we present models in 5D warped spacetime, in which supersymmetry breaking and Higgs fields are located on the ultraviolet and infrared branes, respectively, and the top multiplets are localized to the infrared brane. The hierarchy of the Yukawa matrices can be obtained while keeping near flavor degeneracy between the first two generation sfermions, avoiding stringent constraints from flavor and CP violation. Through the AdS/CFT correspondence, the models can be interpreted as purely 4D theories in which the top and Higgs multiplets are composites of some strongly interacting sector exhibiting nontrivial dynamics at a low energy. Because of the compositeness of the Higgs and top multiplets, Landau pole constraints for the Higgs and top couplings apply only up to the dynamical scale, allowing for a relatively heavy Higgs boson, including m h = 125 GeV as suggested by the recent LHC data. We analyze electroweak symmetry breaking for a well-motivated subset of these models, and find that fine-tuning in electroweak symmetry breaking is indeed ameliorated. We also discuss a flat space realization of the scenario in which supersymmetry is broken by boundary conditions, with the top multiplets localized to a brane while other matter multiplets delocalized in the bulk.

“…One way to address this challenge is to add a singlet superfield whose vacuum expectation value (VEV) generates these terms, as is done in the NMSSM. Unfortunately, previous work on combining gauge or gaugino mediation with the NMSSM has found that the effective shielding of the singlet sector from the supersymmetry breaking also makes it difficult to obtain an acceptable pattern of electroweak symmetry breaking [21]. A number of works have investigated extensions of minimal gauge mediation in the hope of relieving this tension [22,23,24,25].…”

Modified Higgs boson phenomenology from gauge or gaugino mediation in the next-to-minimal supersymmetric standard model

In the Next-to-Minimal Supersymmetric Standard Model (NMSSM), the presence of light pseudoscalars can have a dramatic effect on the decays of the Standard Modellike Higgs boson. These pseudoscalars are naturally light if supersymmetry breaking preserves an approximate U (1) R symmetry, spontaneously broken when the Higgs bosons take on their expectation values. We investigate two classes of theories that possess such an approximate U (1) R at the mediation scale: deformations of gauge and gaugino mediation. In the models we consider, we find two disjoint classes of phenomenologically allowed parameter regions. One of these regions corresponds to a limit where the singlet of the NMSSM largely decouples. The other can give rise to a Standard Model-like Higgs boson with a dominant branching into light pseudoscalars.
