# Proca theory and renormalization

What is the simplest physical argument to claim that Proca theory (involving a massive spin-1 boson) is not renormalizable?

 Isn't it "Proca" with one "c"? – DarenW Nov 14 '11 at 7:06 @DarenW: Yes, Alexandru Proca only has one "c". – Simon Nov 14 '11 at 10:38 @Newman: If Ron's answer is acceptable (and it looks ok to me!), then you should accept it. If not, can you comment on it and say what is missing/wrong? – Simon Dec 1 '11 at 2:49
