嵌入超空间AdS3和AdS4上的超对称模型

Supersymmetric Models on AdS3 and AdS4 Embedding Superspaces

D. G. C. McKeon

摘要:

超空间技术被用来制定一个超对称模型上的AdS3表面嵌入在四维空间。在这个模型中,超对称变换是由AdS3的等距生成器生成的变换的“平方根”。由于动量不是等距生成元,超对称性不会导致玻色子场和它的费米子场质量相等。我们表达这个模型的坐标,表征AdS3空间。在一个坐标系中,可以用Minkowski度量定义子空间。它成为可能,以推断在AdS4空间中的模型,其中有一个对称变换,涉及玻色子和费米场。这个模型不是在超空间中公式化的结果,费米变换也不是AdS4的等距的“平方根”。

英文摘要:

Superspace techniques are used to formulate a supersymmetric model on an AdS3 surface embedded in four dimensions. In this model, the supersymmetry transformation is the "square root" of the transformation generated by the isometry generators of AdS3. Since momentum is not an isometry generator, supersymmetry does not result in equal masses for a Bosonic field and its Fermionic partner. We express this model in terms of coordinates that characterize the AdS3 space. In one coordinate system, it is possible to define a subspace with a Minkowski metric. It becomes possible to infer a model in AdS4 space in which there is a symmetry transformation that relates Bosonic and Fermionic fields. This model is not a consequence of being formulated in superspace and the Fermionic transformation is not the "square root" of an isometry of AdS4.
