利用拓扑孤子动态实现膜世界

Dynamical Realization of the Brane world Scenario Using Topological Solitons

Filip Blaschke

摘要:

在这篇论文中,我们讨论了如何在场论的框架下利用拓扑孤子动态地实现膜世界。我们考虑(4+1)维超对称规范理论的玻色子扇区作为一个操场,它自然地支持余维1的孤子,即畴壁。我们首先讨论了物质场和规范场在畴壁世界体积上的单独定域,然后给出了两个明确的五维模型,其中物质场和规范场都以最小的相互作用定域在一起.我们发现,物质领域本地化的伴随表示的非阿贝尔规范群,我们计算的有效相互作用拉格朗日这些物质领域的二阶导数。我们讨论了我们的模型与QCD中描述π介子的有效模型和弦论中D-膜的相似性。

英文摘要:

In this thesis we discuss how the brane world scenario can be realized dynamically within the field theoretical framework using topological solitons. As a playground we consider a bosonic sector of a (4+1)-dimensional supersymmetric gauge theory, which naturally supports soliton of co-dimension one, a domain wall. We first discuss separate localization of matter fields and gauge fields on the world-volume of the domain wall and then we present two explicit five-dimensional models, where both matter fields and gauge fields are localized together with minimal interactions. We show that matter fields localize in the adjoint representation of the non-Abelian gauge group and we calculate the effective interaction Lagrangian of these matter fields up to the second order in derivatives. We discuss similarities of our models with effective models describing pions in QCD and with D-branes from string theory.
