http://staff.ustc.edu.cn/~xiaozg/QFT2024/lecture-NonAbelian.pdf WebHowever, if we break gauge invariance of the first kind and still maintain gauge invariance of the second kind this reason-ing is obviously incorrect. Indeed, in Fig. 1, one sees that the A propagator connects to in-termediate states, which are "rotated" vacua. This is seen most clearly by writing (y,) =([Qy,]) where Q is the group generator ...
