具有超多重态和边界超势的五维规范超引力的模稳定化

Moduli stabilization in 5D gauged supergravity with universal hypermultiplet and boundary superpotentials

Hiroyuki Abe, 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。在标量流形的八个独立等距中,我们着重于三个方向的引力光子测量。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。我们从有效理论的角度分析了这类模型的真空结构,特别是模量稳定性的性质。我们还讨论了超对称反德西特真空的抬升。

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. Among eight independent isometries of the scalar manifold, we focus on three directions for gauging by the graviphoton. 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 analyze the vacuum structure of such models, especially the nature of moduli stabilization, from the viewpoint of the effective theory. We also discuss the uplifting of supersymmetric anti-de Sitter vacua.
