Static Domain Walls in N = 1 Supergravity
We study supersymmetric domain walls in N=1 supergravity theories, including those with modular-invariant superpotentials arising in superstring compactifications. Such domain walls are shown to saturate the Bogomol’nyi bound of wall energy per unit area. We find static and reflection asymmetric domain wall solutions of the self-duality equations for the metric and the matter fields. Our result...
متن کامل4d, N = 1 Born-infeld Supergravity
We propose the 4D, N = 1 supergravitational analogues (avatars) of the 4D, N = 1 supersymmetric Born-Infeld action in four dimensions for the first time, by using superspace. In particular, a new Born-Infeld type generalization of the Weyl supergravity action is given. A natural new Born-Infeld type generalization of the Einstein supergravity is found as well. We also brielfy discuss a construc...
متن کاملDBI inflation in N 1⁄4 1 supergravity
It was recently demonstrated that, when coupled to N = 1 supergravity, the Dirac-Born-Infeld (DBI) action constructed from a single chiral superfield has the property that when the higher-derivative terms become important, the potential becomes negative. Thus, DBI inflation cannot occur in its most interesting, relativistic regime. In this paper, it is shown how to overcome this problem by coup...
متن کاملN = 1 supergravity reduction in four dimensions
We discuss the reduction of N = 2 supergravity to N = 1, by a consistent truncation of the second gravitino multiplet. It is well known that for globally supersymmetric theories with particle content of spin 0, 1 2 , 1 any theory with N supersymmetries can be regarded as a particular case of a theory with a number N ′ < N of supersymmetries [1]. To prove this it is sufficient to decompose the N...
متن کاملBlack - Hole Attractors in N = 1 Supergravity
We study the attractor mechanism for N = 1 supergravity coupled to vector and chiral multiplets and compute the attractor equations of these theories. These equations may have solutions depending on the choice of the holomorphic symmetric matrix f ΛΣ which appears in the kinetic lagrangian of the vector sector. Models with non trivial electric-magnetic duality group which have or have not attra...
