“…sector, similar to what was done for current correlators in [47][48][49][50][51]. In this case one could derive sum-rules relating the contributions of these poles to the Higgs parameters, obtaining results that are applicable to an even more general class of models.…”

We develop a systematic and general approach to study the effective Higgs Lagrangian in a supersymmetric framework in which the Higgs fields in the visible sector couple weakly to another sector. The extra sector may be strongly coupled in general. It is assumed to be superconformal in the ultraviolet, but develop a mass-gap with supersymmetry breaking in the infrared. The main technique used in our approach is that of the operator product expansion (OPE). By using OPE methods we are able to compute the parameters in the Higgs Lagrangian to quadratic order and make general statements that are applicable to many classes of models. Not only does this approach allow us to understand the traditional problems plaguing simple models from a different perspective, it also reveals new possibilities for solutions of these problems. The methods and results of our work should be useful in constructing a viable and natural model of physics beyond the Standard Model.

“…We swiftly sketch and motivate this relationship which certainly warrants further study on its own. The quiver construction may be related to N = 1 super Yang-Mills (or N = 2 [41][42][43]) in five dimensions [44], which contains a vector multiplet and chiral adjoint V + Φ. Suppose we compactify on four flat dimensions times a small interval of length R. The scalar component of Φ = (Σ + iA 5 ) and in analogy to the quiver, A 5 plays the role of the Goldstone bosons and are eaten to generate the Kaluza-Klein masses such that we may identify 1/R ∼ v of Eqn.…”

The discovery of a 125.5 GeV Higgs with standard model-like couplings and naturalness considerations motivate gauge extensions of the MSSM. We analyse two variants of such an extension and carry out a phenomenological study of regions of the parameter space satisfying current direct and indirect constraints, employing state-of-theart two-loop RGE evolution and GMSB boundary conditions. We find that due to the appearance of non-decoupled D-terms it is possible to obtain a 125.5 GeV Higgs with stops below 2 TeV, while the uncoloured sparticles could still lie within reach of the LHC. We compare the contributions of the stop sector and the non-decoupled D-terms to the Higgs mass, and study their effect on the Higgs couplings. We further investigate the nature of the next-to lightest supersymmetric particle, in light of the GMSB motivated searches currently being pursued by ATLAS and CMS.

“…To extend this work, it would be interesting to explore if warped or holographic scenarios [12,15,45] may also achieve a large A t , as one expects logarithmic [27] rather than power law running in these models. In five dimensions, one may also take advantage of non-decoupled D-terms [46][47][48] such as in [3] to achieve a larger tree level Higgs mass.…”

“…Note also that five dimensional super Yang-Mills have additional matter fields, such as colour adjoint chiral superfields [9,10], compared to its four dimensional counterparts and these can influence the RGEs. Regarding the breaking of supersymmetry, whilst gauge mediation is favoured (and some recent work on gauge mediated supersymmetry breaking in a five dimensional context may be found in [11][12][13][14][15][16][17]), ultimately the universality of squark massses in GMSB mean that even though the gaugino mediated limit [18][19][20][21] might allow for light squarks (and 5D RGE evolution allows for a large A t and the observed Higgs mass), the collider bounds on first and second generation squarks [22,23], in the supra-TeV range would apply also to the 3 rd generation squarks, i.e. the stops, which as discussed before, is both phenomenologically less interesting and unnatural.…”

Even if the unification and supersymmetry breaking scales are around 10 6 to 10 9 TeV, a large A t coupling may be entirely generated at low energies through RGE evolution in the 5D MSSM. Independent of the precise details of supersymmetry breaking, we take advantage of power law running in five dimensions and a compactification scale in the 10 − 10 3 TeV range to show how the gluino mass may drive a large enough A t to achieve the required 125.5 GeV Higgs mass. This also allows for sub-TeV stops, possibly observable at the LHC, and preserving GUT unification, thereby resulting in improved naturalness properties with respect to the four dimensional MSSM. The results apply also to models of "split families" in which the first and second generation matter fields are in the bulk and the third is on the boundary, which may assist in the generation of light stops whilst satisfying collider constraints on the first two generations of squarks.
