超对称Q球与玻色子星的全息双折射

Glueball condensates as holographic duals of supersymmetric Q-balls and boson stars

Betti Hartmann, Juergen Riedel

摘要:

我们研究了四维反德西特时空中的非自旋Q球和玻色子星。我们使用一个指数标量场势,出现在规范介导的超对称性(SUSY)破缺的最小超对称扩展的标准模型(MSSM)。我们研究了这些非拓扑孤子的电荷和质量对负宇宙学常数、周期性时间依赖中出现的频率以及超对称破缺尺度与普朗克质量之比的依赖关系。在标量场函数中没有节点的基本解之后,我们还构造了径向激发解。在本文的第二部分中,我们把重点放在全息解释这些解决方案的玻色-爱因斯坦凝聚体的标量胶球,描述了一个强耦合的量子场论(QFT)的边界上的全球AdS。

英文摘要:

We study non-spinning Q-balls and boson stars in 4-dimensional Anti-de Sitter (AdS) space-time. We use an exponential scalar field potential that appears in gauge-mediated supersymmetry (SUSY) breaking in the minimal supersymmetric extension of the Standard Model (MSSM). We investigate the dependence of the charge and mass of these non-topological solitons on the negative cosmological constant, the frequency that appears in the periodic time-dependence as well as on the ratio between the SUSY breaking scale and the Planck mass. Next to fundamental solutions without nodes in the scalar field function we also construct radially excited solutions. In the second part of the paper we put the emphasis on the holographic interpretation of these solutions in terms of Bose-Einstein condensates of scalar glueballs that are described by a strongly coupled Quantum Field Theory (QFT) on the boundary of global AdS.
