So I may compute the two products and multiply them. What about commutation issues of derivatives of the components of the perturbation field and the field ?

what about just dimensional analysis?

comment Klein-Gordon propagator integral
Hi Thanks. If the integral is for $p_0 \in \mathbb{R}$ is there any problem with the semicircles in both poles? Usually the countour is a semicircle stricly, this more or less the same but not exactly

comment Klein-Gordon propagator integral
Hi thanks. If the poles are displaced from the real axis some $i \epsilon$ then you always get one pole don't you?

comment Klein-Gordon propagator integral
Yes, my particular problem is with the countour of integration, being a semicircle but with two semicircles at $\pm E_p$. Is in page 30 of the book

Yes, I know this is related to residues theorem but I don't see those particular integrals
