二维GCA的超对称扩张

Supersymmetric Extension of GCA in 2d

Ipsita Mandal

摘要:

通过对二维超共形代数进行群压缩,得到了二维时空情形下的无限维超对称伽利略共形代数(SGCA)。我们还得到了超空间坐标下生成元的表示。在这里,我们发现实现的SGCA考虑某些二维SCFT的缩放限制,这是非幺正的,并有他们的左,右中心荷变得大的幅度和相反的符号。我们专注于Neveu-Schwarz部门的父SCFT和发展,并行的GCA研究最近在(arXiv:0912.1090),表示理论的基础上SGCA小学,沃德恒等式为他们的关联函数和他们的后代是空状态。

英文摘要:

We derive the infinite dimensional Supersymmetric Galilean Conformal Algebra (SGCA) in the case of two spacetime dimensions by performing group contraction on 2d superconformal algebra. We also obtain the representations of the generators in terms of superspace coordinates. Here we find realisations of the SGCA by considering scaling limits of certain 2d SCFTs which are non-unitary and have their left and right central charges become large in magnitude and opposite in sign. We focus on the Neveu-Schwarz sector of the parent SCFTs and develop, in parallel to the GCA studies recently in (arXiv:0912.1090), the representation theory based on SGCA primaries, Ward identities for their correlation functions and their descendants which are null states.
