# NLO Corrections/Feynman Diagram

Hello,

I've a question: Does anybody know a book, paper or thesis where I can find a "simple" Loop Correction of a whole process? In every book I only finde the computations of the self-energy and vertex corrections and the derivation of the counterterms, bot not a "whole" process.

I don't know exactly how to work with the new Feynman Rules. I just can imagine a bit^^..
But I'd like to see a whole Computations for the squared amplitude. I would prefer a QED process, but QCD is also ok :)...

I know that I have to add the Counterterm Diagrams to "kill" the divergence of the "loop Diagrams". But how looks the Computation exactly.

Thanks to all und have a nice day.

Regards,

Jodahr
