comment What´s the importance of the normalization of the Kinetic term?
Thanks for point out the mistakes - I corrected them in the question. As for your answer: does it have to do with the $\langle p | \phi | 0 \rangle $ that appears when you are building the LSZ formula? I think I got it but I want to be sure before including my conclusion in the question itself. Being more specific: I guess there will be a $\sqrt{2} \langle p | \phi | 0 \rangle $ in the case of ${\cal L}_2$ but I can't see how it appears without doing field redefinitions.

Good point, not a native English speaker, and automatic orthography correction didn't help me there :D It would be nice to have laser beans though...

comment Surface terms for field path integrals?
So the point here is that the "surface terms" vanish when I integrate with ${\cal L} \rightarrow (1+i \epsilon){\cal L}$, right?

You are right @user1504, I edited it to include the essential formulas

@Terry - maybe you did (forget me) but I didn´t forget the question ;) Great answer by the way! My thanks to everyone involved
