Volkov-Akulov theory and D-branes [PDF]
, 1997 The action of supersymmetric Born-Infeld theory (D-9-brane in a Lorentz covariant static gauge) has a geometric form of the Volkov-Akulov-type. The first non-linearly realized supersymmetry can be made manifest, the second world-volume supersymmetry is ...

Emergence of spontaneously broken supersymmetry on an anti-D3-brane in KKLT dS vacua [PDF]
, 2014 A bstractThe KKLT construction of de Sitter vacua includes an uplifting term coming from an anti-D3-brane. Here we show how this term can arise via spontaneous breaking of supersymmetry, based on the emergence of a nilpotent chiral supermultiplet on the ...

Asymptotic Behavior of Saxion–Axion System in Stringy Quintessence Model
Fortschritte der Physik, Volume 72, Issue 11, November 2024.Abstract The late time behavior of the slow‐roll parameter in the stringy quintessence model is studied when axion as well as saxion are allowed to move. Even though the potential is independent of the axion at tree level, the axion can move through its coupling to the saxion and the background geometry.

Goldstino superfields in AdS_4
, 2013 Spontaneous breaking of global supersymmetries results in Goldstino fields which provide a nonlinear realisation of the supersymmetry algebra. A finite supersymmetry transformation of a Goldstino field can be used to generate a superfield whose ...

Renormalization group flows from holography supersymmetry and a c theorem [PDF]
, 1999 We obtain first order equations that determine a supersymmetric kink solution in fivedimensional N = 8 gauged supergravity. The kink interpolates between an exterior anti-de Sitter region with maximal supersymmetry and an interior anti-de Sitter region ...

de Sitter State in Heterotic String Theory
Fortschritte der Physik, Volume 72, Issue 11, November 2024.Abstract Recent no‐go theorems have ruled out four‐dimensional classical de Sitter vacua in heterotic string theory. On the other hand, the absence of a well‐defined Wilsonian effective action and other related phenomena also appear to rule out such time‐dependent vacua with de Sitter isometries, even in the presence of quantum corrections.

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2015 The article considers the problem of the extension of standard model physics of elementary particles. We focus on nonminimal supersymmetric models. Nowadays this model is the most appropriate compared with other developed supersymmetric theories.

Supersymmetry Breaking, R-Symmetry Breaking and Metastable Vacua
, 2007 Models of spontaneous supersymmetry breaking generically have an R-symmetry, which is problematic for obtaining gaugino masses and avoiding light R-axions.

Supersymmetry and non-Abelian T-duality in type II supergravity [PDF]
, 2014 We study the effect of T-duality on supersymmetry in the context of type II supergravity. For both U(1) Abelian and SU(2) non-Abelian T-duality, we demonstrate that the supersymmetry variations after T-duality are related to the variations before T ...
