Phasenübergänge und Baryogenese im frühen Universum in supersymmetrischen Modellen

有关早期宇宙的重要问题的讨论依赖于目前实验室范围之外的能量物理学，并且可能需要一个超越标准模型的理论。我们想更好地理解重子不对称性的产生和“暗物质”的作用。在这一背景下，我们想要研究单态粒子电弱相变的超对称变体，在Susy模型中从AfflekDine相产生Q球，以及在包括暴胀在内的大统一模型中的瘦子发生。苏西模型的深入讨论包括超重力以及可能与弦理论的联系。

The discussion of important questions about the early universe depends on physics at energies beyond present laboratory bounds and presumably requires a theory beyond the Standard Model. We want to understand better the generation of a baryon asymmetry and the role of "dark matter". In this context we want to work on supersymmetric variants of the electroweak phase transition with singlet particles, on Q-ball production from an AfflekDine phase in Susy models, and on leptogenesis in grand unified models including inflation. The thorough discussion of Susy models includes supergravity and possibly connections with string theory.
