无费密子格点规范理论几种新作用量的探讨

我们提出了几种无费密子格点规范理论的新作用量形式,证明了它们符合Wilson对格点作用量提出的条件,讨论了它们与几种常用的作用量间的关系。并推导了在使用新作用量时Wilson圈满足的Schwinger-Dyson方程,证实了当N→∞时,E-K模型中的Schwinger-Dyson方程和标准格点模型相同。 关键词：

SOME ALTERNATIVE ACTIONS IN PURE LATTICE GAUGE THEORY

In lattice gauge theory some alternative actions without fermions were proposed, which obey Wilson's conditions for lattice action and were related with usually adopted actions. The Schwinger-Dyson equation obeyed by Wilson loop amplitude with the alternative actions was derivated. We verified that, in large N limit in E-K reduced model, the same Schwinger-Dyson equation exists as in the standard model.
