Fermionic propagator [closed]
Given the fermionic generating functional $$Z[\eta]=\
det^{\frac{1}{2}}(K_{ij})e^{-\frac{i}{2}\eta_{i}G^{ij}\eta_{j}},\tag{1}$$ where $$G^{ij}=K^{-1}_{ij}$$ is the Green function of our theory, then w …

BRST charge action on fields
How can we prove that the BRST charge $Q$ acts on bosonic fields as $$\delta A(x) = \epsilon[Q,A(x)]\tag{1}$$ and on fermionic fields as $$\delta\psi(x) = \epsilon\{Q, \psi(x)\}\tag{2}.$$
And how sh …
