# Interactive fields in QFT - the φ^3 example

Does anybody knows a textbook, a paper or any lecture notes that discusses the $$\phi^3$$ interactive field? I use as main reference Ryder's QFT, which discusses only the $$\phi^4$$ interaction. And most similar textbooks (like Peskin's, Brown's etc.) do so.

I have derived the point functions and currently trying to renormalize the $$\phi^3$$ theory, so I'd like to compare my results with the right ones. Thanx!

It's discussed in many books. Take a look at this draft of a QFT book by Srednicki:

Sterman's QFT book also discusses phi-3 theory, so does Muta's QCD book.

Thanx a lot!
