Large N expansion

  1. Mar 14, 2014 #1

    Apparently for SU(N) gauge theories there is a perturvative approach call "large N expansion". I need a working knowledge of this method but I can not find it in any textbook only in research papers that are rather for the expert. Someone has any suggestion where should I get started?
    Can it be found in Weinberg's?

    Thank you in advance

    Zee, QFT in a Nutshell, gives a short (3 pages) introduction to the idea.

    I always liked some notes by Manohar http://arxiv.org/abs/hep-ph/9802419. The first several sections are generic, discussing both vector and matrix large N, while the later sections get into more detailed QCD physics.

    Thank you very much. I already knew about Zee's but is too short I will give now a try to Manohar.
