re: #992 Kosh’s Shadow

Reminds me of when I took quantum field theory and we learned about renormalization.

Then there’s dimensional regularization, probably equally objectionable. You get an integral which diverges in 4 dimensions. So, integrate it in d dimensions where d is complex and where the integral is no longer divergent, or at least allows you to pull out a non-divergent piece plus “something nasty” like a gamma function or two. Then, analytically continue back to 4 dimensions and there’s your answer. Did I get that right? I think that the co-inventor (Gerard ‘t Hooft) used this technique to show that the GWS theory was renormalizable, or have I got my gluons crossed?
