超对称不变理论

Supersymmetric invariant theories

S. R. Esipova, P. M. Lavrov, O. V. Radchenko

摘要:

我们研究场模型的量子作用(即出现在生成功能的格林函数)是不变的超对称变换。我们导出了沃德恒等式,它是这种不变性的直接结果。本文讨论了与超对称变换有关的泛函积分中的变量变换,当其参数用场的幂零泛函代替时。当给定的场论存在一致的量子描述时,我们发现了超对称变换生成元的限制。

英文摘要:

We study field models for which a quantum action (i.e. the action appearing in the generating functional of Green functions) is invariant under supersymmetric transformations. We derive the Ward identity which is direct consequence of this invariance. We consider a change of variables in functional integral connected with supersymmetric transformations when its parameter is replaced by a nilpotent functional of fields. Exact form of the corresponding Jacobian is found. We find restrictions on generators of supersymmetric transformations when a consistent quantum description of given field theories exists.
