高维场论中的β函数

beta-functions in higher dimensional field theories

J. A. Gracey

摘要:

本文综述了六维及更高维O(N)标量和规范理论的重整化群函数的构造。这些理论在威尔逊-费雪不动点上属于它们各自的普适类。在这个不动点的临界指数在各个维度都与已知的指数确定的大N展开。

英文摘要:

We review recent activity in the construction of the renormalization group functions for O(N) scalar and gauge theories in six and higher dimensions. The theories lie in their respective universality classes at the Wilson-Fisher fixed point. The critical exponents at this fixed point in the various dimensions are all in agreement with the known exponents determined in the large Nexpansion.
