基于BRST不变性原理，我们重新讨论了规范固定和鬼点的一般过程。结果表明，当这是适用于较高的导数规范固定，它给出了正确的结构规范固定和鬼，包括“第三鬼”，以前在一个循环的水平。这个过程完全基于对称性原理，并且在全阶下有效。
We revisit the general procedure of gauge fixings and ghosts based on BRST invariance principle. It is shown that when this is applied to the higher-derivative gauge fixings, it gives the correct structure of gauge fixings and ghosts including “third ghost”, previously derived at one-loop level. This procedure is solely based on the symmetry principle and is valid at full order.
