TL;DR: In this article, the authors studied supersymmetric quantum mechanics with particular emphasis on scattering relations and coupled channels, and they discussed channels with different masses, the threshold behavior of S-matrix partners, phase equivalence, and the appearance and disappearance of Smatrix poles.
Abstract: We study supersymmetric quantum mechanics with particular emphasis on scattering relations and coupled channels. We discuss channels with different masses, the threshold behavior of supersymmetric S-matrix partners, phase equivalence, and the appearance and disappearance of S-matrix poles. We also present some soluble examples.

TL;DR: In this article, the dynamics of N = 1 supersymmetric systems consisting of the strongly-coupled superconformal theory T_N, SU(N) gauge groups, and fundamental chiral multiplets are studied.
Abstract: We study the dynamics of N=1 supersymmetric systems consisting of the strongly-coupled superconformal theory T_N, SU(N) gauge groups, and fundamental chiral multiplets. We demonstrate that such systems exhibit familiar phenomena such as deformation of the vacuum moduli space, appearance of the dynamical superpotential, and Coulomb branches with N=1 Seiberg-Witten curves. The analysis requires a rather detailed knowledge of the chiral ring of the T_N theory, which will also be discussed at length.

TL;DR: In this paper, the landscape of flux compactifications for the Calabi-Yau manifold with two Kahler moduli was scanned by varying the value of the flux superpotential W0 over a large range of values.
Abstract: We scan the landscape of flux compactifications for the Calabi-Yau manifold 4[1,1,1,6,9] with two Kahler moduli by varying the value of the flux superpotential W0 over a large range of values. We do not include uplift terms. We find a rich phase structure of AdS and dS vacua. Starting with W0 ~ 1 we reproduce the exponentially large volume scenario, but as W0 is reduced new classes of minima appear. One of them corresponds to the supersymmetric KKLT vacuum while the other is a new, deeper non-supersymmetric minimum. We study how the bare cosmological constant and the soft supersymmetry breaking parameters for matter on D7 branes depend on W0, for these classes of minima. We discuss potential applications of our results.

TL;DR: In this paper, a general de Sitter supergravity action with a given potential K, superpotential W, and vectormatrix fAB interacting with a nilpotent chiral multiplet was derived.
Abstract: The de Sitter supergravity describes the interaction of supergravity with general chiral and vector multiplets and also one nilpotent chiral multiplet. The extra universal positive term in the potential, generated by the nilpotent multiplet and corresponding to the anti-D3 brane in string theory, is responsible for the de Sitter vacuum stability in these supergravity models. In the flat-space limit, these supergravity models include the Volkov–Akulov model with a nonlinearly realized supersymmetry. We generalize the rules for constructing the pure de Sitter supergravity action to the case of models containing other matter multiplets. We describe a method for deriving the closed-form general supergravity action with a given potential K, superpotential W, and vectormatrix fAB interacting with a nilpotent chiral multiplet. It has the potential V = eK(|F2|+|DW|2-3|W|2), where F is the auxiliary field of the nilpotent multiplet and is necessarily nonzero. The de Sitter vacuums are present under the simple condition that |F2|-3|W|2 > 0. We present an explicit form of the complete action in the unitary gauge.

TL;DR: In this article, an R + R n class of modified N = 1, D = 4 supergravity models where the deformation is a monomial R n | F in the chiral scalar curvature multiplet R of the old minimal auxiliary field formulation is discussed.
