[Modèles de D-branes et brisure de supersymétrie par flux.]
Nous décrivons des travaux récents de constructions de modèles de cordes à 4 dimensions ayant des modules stabilisés par des flux, ainsi que des secteurs chiraux de jauge proches du modèle standard, réalisés à partir de configurations de D-branes. Nous expliquons comment les liens entre les différents ingrédients relient des aspects phénoménologiques, en particulier l'apparition de termes doux dans le secteur de jauge des D-branes à partir de champs de fonds non-supersymétriques avec flux.
We describe recent work on constructing four-dimensional string models with moduli stabilized by field strength fluxes and chiral gauge sectors close to the Standard Model from D-brane configurations. We discuss how the interplay of both ingredients relates to phenomenological issues, in particular the appearance of soft terms on the D-brane gauge sector induce from non-supersymmetric flux backgrounds.
