因果方法中的反BRST

Anti-BRST in the Causal Approach

D. R. Grigore

摘要:

众所周知,在微扰论的所有阶数中消除反常是一个公开的问题。通常的不变性性质和Wess-Zumino恒等式给出的约束不足以消除杨-米尔斯理论的一般情况下的异常。因此,模型的任何新的对称性都可以进一步限制异常,并成为问题的解决方案。我们认为反BRST变换的大岛在因果关系的方法,并调查,如果这样的新的限制。不幸的是,结果是否定的:如果我们有BRST不变性到二阶微扰理论,我们也有反BRST不变性到相同的顺序。这个结果在微扰论的所有阶次中可能都是正确的。因此,反BRST变换并没有给出什么新的东西,我们必须找到其他的思想来限制并最终消除一般杨-米尔斯理论的异常。

英文摘要:

It is known that the elimination of the anomalies in all orders of perturbation theory is an open problem. The constrains given by usual invariance properties and the Wess-Zumino identities are not enough to eliminate the anomalies in the general case of an Yang-Mills theory. So, any new symmetry of the model could restrict further the anomalies and be a solution of the problem. We consider the anti-BRST transform of Ojima in the causal approach and investigate if such new restrictions are obtained. Unfortunately, the result is negative: if we have BRST invariance up to the second order of the perturbation theory, we also have anti-BRST invariance up to the same order. Probably, this result is true in all orders of the perturbation theory. So, anti-BRST transform gives nothing new, and we have to find other ideas to restrict and eventually eliminate the anomalies for a general Yang-Mills theory.
