TL;DR: In this paper, the nonlinear supersymmetry of one-dimensional systems is investigated in the context of the quantum anomaly problem, and the most general one-parametric Calogero-like solution with the second order supercharges is found.

TL;DR: In this article, the authors derive the effective N = 1 supergravity theory associated to the type IIA orientifolds with D6 branes, compactified on T6/(Z2× Z2).
Abstract: We illustrate the correspondence between the N =1 superstring compactifications with fluxes, the N = 4 gauged supergravities and the superpotential and Kahler potential of the effective N = 1 supergravity in four dimensions. In particular we derive, in the presence of general fluxes, the effective N = 1 supergravity theory associated to the type IIA orientifolds with D6 branes, compactified on T6/(Z2× Z2). We construct explicit examples with different features: in particular, new IIA no-scale models, new models with cosmological interest and a model which admits a supersymmetric AdS4 vacuum with all seven main moduli (S, TA, UA,A = 1,2,3) stabilized.

TL;DR: In this paper, it was shown that a supersymmetric U(N) gauge theory with adjoint matter Φ and a polynomial superpotential Tr W(Φ) has a continuous (and holomorphic) fashion.
Abstract: = 1 supersymmetric U(N) gauge theory with adjoint matter Φ and a polynomial superpotential Tr W(Φ) has been much studied recently. The classical theory has several vacua labeled by integers (N1, N2, ..., Nk), with the classical unbroken gauge group ∏iU(Ni). Quantum mechanically, each classical vacuum leads to ∏iNi different vacua. As the parameters of W(Φ) are varied, these vacua change in a continuous (and holomorphic) fashion. We find that vacua associated with (N1, N2, ..., Nk) can be continuously transformed to vacua with (N1, N2, ..., Nk), thus leading to a new kind of duality. Traditional order parameters, like the Wilson loop and 't Hooft loop, sometimes distinguish different phases. We also find phases that are not distinguished by conventional order parameters. The whole picture of the phase diagram is reminiscent of the phase diagram of M-theory.

TL;DR: In this paper, the breaking of N = 1 supersymmetry by non-zero G-flux when M-theory is compactified on a smooth manifold X of G_2 holonomy is considered.
Abstract: We consider the breaking of N=1 supersymmetry by non-zero G-flux when M-theory is compactified on a smooth manifold X of G_2 holonomy. Gukov has proposed a superpotential W to describe this breaking in the low-energy effective theory. We check this proposal by comparing the bosonic potential implied by W with the corresponding potential deduced from the eleven-dimensional supergravity action. One interesting aspect of this check is that, though W depends explicitly only on G-flux supported on X, W also describes the breaking of supersymmetry by G-flux transverse to X.

TL;DR: In this paper, the Wess-Zumino model is extended to a deformed superspace in which the coordinates do not anticommute, but satisfy a Clifford algebra.
Abstract: We consider a deformed superspace in which the coordinates \theta do not anticommute, but satisfy a Clifford algebra. We present results on the properties of N=1/2 supersymmetric theories of chiral superfields in deformed superspace, taking the Wess-Zumino model as the prototype. We prove new (non)renormalization theorems: the F-term is radiatively corrected and becomes indistinguishable from the D-term, while the Fbar-term is not renormalized. Supersymmetric vacua are critical points of the antiholomorphic superpotential. The vacuum energy is zero to all orders in perturbation theory. We illustrate these results with several examples.
