Dec 6, 2022 at 16:32 | comment | added | leob | Thank you, this clears up a lot. However I'd like to check my understanding. You state we must fix some choice of gauge in order to proceed. This then reduces our symmetry group from $\mathcal{G}$ to $G$, which is why ‘Higgsing’ involves an unbroken subgroup $H$ viewed as a subgroup of $G$ rather than $\mathcal{G}$, etc. Am I correct in saying the reason we must fix a gauge because otherwise our system can’t distinguish between gauge equivalent states? | |
