关于AdS(d)中的维数递减

On Dimensional Degression in AdS(d)

A. Yu. Artsukevich, M. A. Vasiliev

摘要:

我们利用d维anti-de Sitter空间中的场来分析d+1维anti-de Sitter空间中的场的模式。这个过程既不是降维,也不是维数紧化,称为维数递减。分析进行群论的所有完全对称玻色子和费米子表示的反德西特代数。对AdS(d+d $^\prime$)中的有质量标量场和AdS(d+1)中的无质量自旋二分之一场、自旋一场和自旋二场进行了场论分析.本文给出了AdS(d)中由此产生的场塔的质量谱,对于标量场,所得结果推广到了阴影区.

英文摘要:

We analyze the pattern of fields in d+1 dimensional anti-de Sitter space in terms of those in d dimensional anti-de Sitter space. The procedure, which is neither dimensional reduction nor dimensional compactification, is called dimensional degression. The analysis is performed group-theoretically for all totally symmetric bosonic and fermionic representations of the anti-de Sitter algebra. The field-theoretical analysis is done for a massive scalar field in AdS(d+d$^\prime$) and massless spin one-half, spin one, and spin two fields in AdS(d+1). The mass spectra of the resulting towers of fields in AdS(d) are found. For the scalar field case, the obtained results extend to the shadow sector those obtained by Metsaev in [1] by a different method.
