Orbifold上5D SUGRA模型的半径稳定性

Radius stabilization in 5D SUGRA models on orbifold

Yutaka Sakamura

摘要:

研究了在轨道不动点处具有泛超多重态和微扰超势项的四维五维规范超引力有效理论。我们考虑的一类模型包括5D杂种M-理论和超对称Randall-Sundrum模型作为测量参数的特殊限制。从有效理论的角度分析了模型的真空结构,特别是模量稳定化的本质。

英文摘要:

We study a four-dimensional effective theory of the five-dimensional (5D) gauged supergravity with a universal hypermultiplet and perturbative superpotential terms at the orbifold fixed points. The class of models we consider includes the 5D heterotic M-theory and the supersymmetric Randall-Sundrum model as special limits of the gauging parameters. We analyse the vacuum structure of the models, especially the nature of the moduli stabilization, from the viewpoint of the effective theory.
