i've never had a QM class let alone QFT, i've only even had intro physics 1 & 2, but i've been given a problem that is very similar to this:

[tex]-ie^3 \int {d^4 q \over (2\pi)^4} \gamma^\mu {i (\gamma^\alpha (r-q)_\alpha + m) \over (r-q)^2 - m^2 + i \epsilon} \gamma^\rho {i (\gamma^\beta (p-q)_\beta + m) \over (p-q)^2 - m^2 + i \epsilon} \gamma^\nu {-i g_{\mu\nu} \over q^2 + i\epsilon }[/tex]

it's obviously not essential i know how to do this for a test or anything, but what can i read to be able to begin to attack this problem? i've the sections from peskin and shroeder on feyman parameters and dimensional regularization but i can't really make sense of those either.

any ideas? i'm going to be talking to one of my professors about it on monday hopefully.
