I've studied a lot of literature on Feymann integrals and have usually found them lacking or simply don't describe the steps to solving them in great detail. I recently came across a reference that I am thoroughly enjoying the scope of how it details the integrals in a wide range of related theories.  (warning extremely math intense). If anyone wants a good solid reference I highly recommend this article.

Do you seriously call this 800+ page tome an “article”  

Great resource though +1

PS. Why does the upvote I just gave you appear in red, instead of green? I’ve never seen this happen before…

Looks to me like you have now understood it and fixed it.
