关于$AdS_{4}\times \mathbb{CP}^{3}$中对偶巨引力子的注记

高能物理 - 理论 2010-01-15 v3

摘要

我们研究了在AdS4×CP3AdS_{4}\times \mathbb{CP}^{3}上的IIA型弦理论中,对偶巨引力子(包裹在S2AdS4S^{2}\subset AdS_{4}上的D2膜)的一些性质。我们特别证实了关于巨子的小涨落谱是实的,并且与引力子的大小无关。我们还将先前发展的将开弦附着到巨子上的技术推广到该D2膜巨子,并关注所得弦西格玛模型的两个特定极限:在pp波极限中,我们量子化弦并计算玻色子激发谱;在半经典极限中,我们读出快弦Polyakov作用量,并评论与对偶开自旋链的Landau-Lifshitz作用量的比较。

v3 significantly changed: added coupling to RR 1-form and turned on worldvolume gauge field, computed gauge field fluctuation, added comments on closure of the sl(2) sector and re-written to improve clarity. This version published in JHEP
