“…The constraints (2.3a) and (2.3b) were derived for the first time by Wess [37] as a generalisation of the N = 1 construction [9]. The constraints (2.3) tell us that ξ α i = Ξ α i | θ=0 andψ iα =Ψ iα | θ=0 are the only independent component fields contained in the Goldstino superfields introduced.…”

“…In particular, the absence of scalars is an attractive feature for phenomenological applications. Some of the N = 2 superfield Goldstino models given in [1] have natural N = 1 counterparts [6][7][8][9][10]. In particular, the constrained chiral scalar superfield, which will be reviewed in section 2.2, is the N = 2 analogue of the N = 1 chiral scalar superfield φ [6,7], Dαφ = 0, which is subject to the constraints [6]:…”

We present off-shell N = 2 supergravity actions, which exhibit spontaneously broken local supersymmetry and allow for de Sitter vacua for certain values of the parameters. They are obtained by coupling the standard N = 2 supergravity-matter systems to the Goldstino superfields introduced in arXiv:1105.3001 and arXiv:1607.01277 in the rigid supersymmetric case. These N = 2 Goldstino superfields include nilpotent chiral and linear supermultiplets. We also describe a new reducible N = 1 Goldstino supermultiplet.

“…Control of the semiclassical limit requires δ 1, 8 One might wonder how supergravity can couple to such a system, but this can be done by using an equivalent formulation wherein global supersymmetry is nonlinearly realized [27][28][29][30][31][32] by appropriately coupling a Goldstone fermion on the brane, and then coupling this to supergravity using standard Noether methods. In the end the Goldstone fermion is eaten by the super-Higgs mechanism [33][34][35][36] to give a mass to the massless KK mode of the bulk gravitino.…”

Abstract:We identify the underlying symmetry mechanism that suppresses the lowenergy effective 4D cosmological constant within some 6D supergravity models, generically leading to results suppressed by powers of the KK scale, m 2 KK , relative to the much larger size, m 4 , associated with mass-m particles localized in these models on codimension-2 branes. These models are examples for which the local conditions for unbroken supersymmetry can be satisfied locally everywhere within the extra dimensions, but are obstructed only by global conditions like flux quantization or by the mutual inconsistency of the boundary conditions required at the various branes. Consequently quantities (like vacuum energies) forbidden by supersymmetry cannot become nonzero until wavelengths of order the KK scale are integrated out, since only such long wavelength modes can see the entire space and so 'know' that supersymmetry has broken. We verify these arguments by extending earlier rugby-ball calculations of one-loop vacuum energies within these models to more general pairs of branes within two warped extra dimensions. JHEP07 (2014)034 numerical purposes we take m to be the top-quark mass and take M g as small as possible, consistent with energy-loss bounds from supernovae.) C is a constant depending on the details of the bulk spectrum, which could easily be of order 500 for each of hundreds of fields in the bulk. The value C ∼ 6 × 10 6 would give the observed Dark Energy density.

In this paper we use nonlinear realizations to examine the breaking of N = 2 extended supersymmetry to N = 1. We derive Lagrangians and transformations laws for the generalized N = 2 Akulov-Volkov Goldstone field. We analyze the ghost states and show that they may be collected into N = 1 supermultiplets. We extend the transformation laws for the N = 1 chiral and vector multiplets to N = 2. Finally, we give the N = 2 generalization of an arbitrary N = 1 supersymmetric Lagrangian.
