Operator product expansion

  1. Aug 27, 2011 #1
    hello,
    I'm trying to find a good and exaustive explanation of operator product expansion.
    I've read "renormalization" and weinberg but i continue to not understand ope in interacting field theory.
    someone could help me?

    Do you have a specific question? Also, have you read the big yellow book (Francesco)?

    Yes but explain only conformal field theory.
    For example I'm not able to wright down the ope for \lamda \phi^4. I don't know how to start

    Sorry, I don't know anything about OPEs for non-conformal theories.
