变形背景上的巨人第II部分:规范场涨落

Giants on Deformed Backgrounds Part II: The Gauge Field Fluctuations

Marco Pirrone

摘要:

我们研究了完全边缘变形背景下的巨引力子和双巨引力子探测器周围的全玻色子谱。考虑AdS_5 × S^5的超对称和非超对称三参数形变,我们对两种扩展D3-膜组态的小涨落进行了详细的分析。特别地,我们利用规范场涨落的重要贡献,增强了在我们先前的论文hep-th/0609173中发现的频率的标量谱。巨引力子的情况下,表现出非平凡的标量和矢量模式之间的耦合驱动的变形,其分辨率产生的未变形的频谱的普遍校正。另一方面,双巨振动是完全解耦的。从我们的结果也可以很容易地读出未变形(对偶)巨引力子情形下的规范场涨落。

英文摘要:

We study the full bosonic spectrum around giant and dual giant graviton probes in exactly marginally deformed backgrounds. Considering supersymmetric and non-supersymmetric three-parameter deformations of AdS_5 X S^5, we perform a detailed analysis of small fluctuations for both the expanded D3-brane configurations. In particular, we enhance the scalar spectra of frequencies found in our previous paper hep-th/0609173 with the important contributions brought by the gauge field fluctuations. The giant graviton case exhibits a non-trivial coupling between scalar and vector modes driven by the deformation, whose resolution yields to a universal correction of the undeformed spectrum. On the other hand, dual giant vibrations turn out to be completely decoupled. From our results one can also easily read the gauge field fluctuations in the undeformed (dual) giant graviton scenario.
