Aug 18, 2019 at 15:39 comment added NDewolf Oh ok i see. What I thought was that they meant that for internal loops one just traces over all possible particle types and that this induced the divergences.
Aug 18, 2019 at 15:18 comment added AccidentalFourierTransform ... so, where do the divergences come from? you may want to check What is the issue with interactions in QFT? for a discussion.
