Abstract:
We first give a proof that the supersymmetric configurations satisfy the equations of motion for type II supergravity. In flux compactifications, the string vacua preserving N = 2 supersymmetry are the twisted generalized Calabi–Yau manifold. The modulus space of the string vacua can be constructed. We discuss the generalized Dirac operator which adds a torsional term to the ordinary Dirac operator and compute its index by the path integral method. Via the variation of the action of supergravity one can introduce the generalized Ricci flow equations. We consider deforming the manifold with the

Abstract:
Abstract We use exceptional field theory to systematically study all possible consistent truncations around any M-theory half-maximal vacua of the warped product form AdS5 × M 3 × S 2 × S 1, with M 3 a three-dimensional manifold. We show that, for any of these vacua, only truncations with at most three vector multiplets are consistent. Furthermore, the possible gaugings are restricted to be either SU(2) × U(1) or ISO(3) × U(1) where, in the first case, the U(1) factor can have different embeddings inside the global symmetry group SO(5, n), where n ⩽ 3 equals the number of vector multiplets.

Abstract:
The search for semi-realistic supergravity models, seen as the low-energy limit of superstring theory, strongly motivates the study of gauged supergravities and flux compactifications. Outstanding problems in this context are supersymmetry breaking, moduli stabilization and the generation of a small positive vacuum energy density. Whilst spontaneously broken N=1 supergravity is the only phenomenologically viable possibility in four dimensions, its vast arbitrariness is significantly reduced when considering consistent truncations of extended supergravities or, more generally, effective theorie

Abstract:
This thesis is devoted to the study of specific solutions in extended supergravity theories. In the first introductory Chapter, we analyze the basic ideas underlying supersymmetry and supergravity models, focusing on the idea of supergravity as a powerful effective low energy approach to more fundamental underlying theories like superstring/M-theory. Subsequently, the thesis is divided into two parts: a first one (consisting in Chapter 2 and 3) in which black hole solutions to ungauged supergravity models are discussed; a second remaining part (Chapter 4 and 5) in which we analyze the constru

Depuis la découverte que l'expansion de notre univers est probablement entraînée par l'énergie du vide, la recherche de vides de Sitter en quatre dimensions dans la théorie des cordes est devenue un des principaux objectifs de la phénoménologie des cordes. Cependant, malgré deux décennies d'efforts, la construction de vides de Sitter métastables reste un grand défi, et la construction vieille de vingt ans de Kachru, Kallosh, Linde et Trivedi (KKLT), bien que controversée, demeure un des exemples prototypes. Le scénario KKLT est une construction en deux étapes, où, dans un premier temps, la thé

Abstract:
In the context of supergravity, the Romans mass is a scalar flux which has been shown to have peculiar properties as avoiding uplifting to M-theory; moreover, in several models it has been used in order to fix moduli. We show that the singularity in SuperGravity due to the O6 plane, that for a vanishing Romas mass is resolved in M-theory, is canceled by the presence of the Romans mass. The result has been obtained using the Generalized Complex Geometry formalism in SuperGravity. The same phenomenon is shown from the gauge theory point of view: the metric near the O6 in the massless case is the

Ces solutions sont intéressantes pour relier la théorie des cordes à une extension supersymétrique (SUSY) du modèle standard des particules, ou à des modèles cosmologiques.
