“…In particular, if we choose α 1 = α 2 = α ′ 1 = α ′ 2 = 0, the resulting theory possesses unbroken 4D N = 1 supersymmetry, whose transformation parameter is given by ξ 1 (x µ , y) = exp(−σ/2)ξ L where ξ L is a spinor (dependent on coordinates in supergravity) subject to the condition γ 5 ξ L = ξ L . The explicit realization of this case in the context of supergravity has been extensively studied [27].…”

Explicit supersymmetry breaking on boundaries of warped extra dimensions

Explicit supersymmetry breaking is studied in higher dimensional theories by having boundaries respect only a subgroup of the bulk symmetry. If the boundary symmetry is the maximal subgroup allowed by the boundary conditions imposed on the fields, then the symmetry can be consistently gauged; otherwise gauging leads to an inconsistent theory. In a warped fifth dimension, an explicit breaking of all bulk supersymmetries by the boundaries is found to be inconsistent with gauging; unlike the case of flat 5D, complete supersymmetry breaking by boundary conditions is not consistent with supergravity. Despite this result, the low energy effective theory resulting from boundary supersymmetry breaking becomes consistent in the limit where gravity decouples, and such models are explored in the hope that some way of successfully incorporating gravity can be found. A warped constrained standard model leads to a theory with one Higgs boson with mass expected close to the experimental limit. A unified theory in a warped fifth dimension is studied with boundary breaking of both SU (5) gauge symmetry and supersymmetry. The usual supersymmetric prediction for gauge coupling unification holds even though the TeV spectrum is quite unlike the MSSM. Such a theory may unify matter and Higgs in the same SU (5) hypermultiplet.

“…This result ensures that the Randall-Sundrum scenario may be realized in a fully supersymmetric context. Despite some initial no-go theorems [19,20] and difficulty in supersymmetrizing the brane-world in a pure N = 2 supergravity context [21], it has subsequently been seen that these difficulties are overcome through the incorporation 1 Such types of solutions were first considered in D = 4, N = 1 supergravity in [3]. For a review, see [4] of the breathing mode, and by appealing to the higher-dimensional origin of the underlying gauged five-dimensional supergravity [17,22,23].…”

We show that the singular sources in the energy-momentum tensor for the RandallSundrum brane world, viewed as a solution of type IIB supergravity, are composed of two elements. One of these is a D3-brane source with tension opposite in sign to the RS tension in five dimensions; the other arises from patching two regions of flat ten-dimensional spacetime. This resolves an apparent discrepancy between supersymmetry and the sign and magnitude of the RS tension.

Radiative Scherk–Schwarz supersymmetry breaking

We analyze the Scherk-Schwarz (SS) supersymmetry breaking in brane-world five dimensional theories compactified on the orbifold S 1 /Z 2 . The SS breaking parameter is undetermined at the tree-level (no-scale supergravity) and can be interpreted as the Hosotani vacuum expectation value corresponding to the U (1) R group in five dimensional N = 2 (ungauged) supergravity. We show that the SS breaking parameter is fixed at the loop level to either 0 or 1/2 depending on the matter content propagating in the bulk but in a rather model-independent way. Supersymmetry breaking is therefore fixed through a radiative Scherk-Schwarz mechanism. We also show that the two discrete values of the SS parameter, as well as the supersymmetry breaking shift in the spectrum of the bulk fields, are altered in the presence of a brane-localized supersymmetry breaking arising from some hidden sector dynamics. The interplay between the SS and the brane localized breaking is studied in detail.
