论文摘要
我们根据BRST不变性原理重新审查规格固定和幽灵的一般程序。结果表明，当将其应用于更高衍生的量规固定剂时，它提供了正确的量规固定和幽灵的结构，包括先前在一环级别得出的“第三个幽灵”。此过程仅基于对称原理，并且在完全顺序上有效。
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.
