巨引力子-带弦(III)

Giant Gravitons - with Strings Attached (III)

David Bekker, Robert de Mello Koch, Michael Stephanou

摘要:

我们发展了计算${\cal N}=4$超杨-米尔斯理论中算符的单圈反常维数的技术,这些算符是以球巨引力子的束缚态为终点的开弦的对偶。我们的结果,这是适用于激发涉及任意数量的开弦,推广了单弦的结果hep-th/0701067。我们考虑的开弦在嵌入AdS $_5\times$ S $^5$背景的S $^5$中的S $^3$上携带角动量。用对角化相互作用Cuntz振子哈密顿量的问题代替了计算单圈反常维数的问题。我们的Cuntz振子动力学说明了在多膜上传播的开弦的Chan-Paton因子是如何动态产生的。

英文摘要:

We develop techniques to compute the one-loop anomalous dimensions of operators in the ${\cal N}=4$ super Yang-Mills theory that are dual to open strings ending on boundstates of sphere giant gravitons. Our results, which are applicable to excitations involving an arbitrary number of open strings, generalize the single string results of hep-th/0701067. The open strings we consider carry angular momentum on an S$^3$ embedded in the S$^5$ of the AdS$_5\times$S$^5$ background. The problem of computing the one loop anomalous dimensions is replaced with the problem of diagonalizing an interacting Cuntz oscillator Hamiltonian. Our Cuntz oscillator dynamics illustrates how the Chan-Paton factors for open strings propagating on multiple branes can arise dynamically.
