量子场论中规范不变性问题的新认识
A new look at the problem of gauge invariance in quantum field theory
摘要：
假设量子场论是规范不变的。然而，众所周知，当某些量使用微扰理论计算时，结果不是规范不变的。为了得到物理上正确的结果，必须去掉非规范不变项。在本文中，我们将研究这个问题，并确定为什么一个理论，应该是规范不变产生非规范不变的结果。
英文摘要：
Quantum field theory is assumed to be gauge invariant. However it is well known that when certain quantities are calculated using perturbation theory the results are not gauge invariant. The non-gauge invariant terms have to be removed in order to obtain a physically correct result. In this paper we will examine this problem and determine why a theory that is supposed to be gauge invariant produces non-gauge invariant results.
