Résumé
Abstract

Les progrès théoriques récents et les mesures expérimentales à venir rendent possibles les tests des prédictions cosmologiques génériques de la théorie des cordes. Les modèles branaires et anti-branaires d'inflations sont des description cordistes prometteuses de la physique des l'univers primordial. Bien que variants dans leurs constructions, ces modèles ont tous la conséquence générique et importante que les cordes cosmiques sont abondantes dans l'univers primordial. Ceci donne des effets détectables dans le rayonnement du fond cosmique, la physique des ondes gravitationnelles et les effets de lentille gravitationnelle. Des calculs détaillés dans la cadre de la théorie des cordes des interactions entre les cordes cosmiques sont présentés, afin de différentier ces cordes cosmiques de celles des théories plus conventionnelles ; la probabilité de ces interactions peut être tres différente des cordes conventionnelles en 4D, fournissant des possibilités de tests expérimentaux de la théorie des cordes.

Recent theoretical advances and upcoming experimental measurements make the testing of generic predictions of string theory models of cosmology feasible. Brane anti-brane models of inflation within superstring theory are promising as string theory descriptions of the physics of the early universe. While varied in their construction, these models can have the generic and observable consequence that cosmic strings will be abundant in the early universe. This leads to possible detectable effects in the cosmic microwave background, gravitational wave physics and gravitational lensing. Detailed calculations of cosmic string interactions within string theory are presented, in order to distinguish these cosmic strings from those in more conventional theories; these interaction probabilities can be very different from conventional 4D strings, providing the possibility of experimental tests of string theory.
