To understand QCD Vacuum

  1. Jan 7, 2016 #1
    How to understand QCD vacuum? What is the model independent expectation value for it? Looking for some basic literature on it.

    Thanks in advance!

    Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?

    The question is a bit vague to me, but for example a place where a discussion on the QCD vacuum can be found is:


    Peccei was one of the "inventors" of the Axion in order to provide a solution of the so called strong CP problem, which arises precisely due to the structure of the QCD vacuum.

    I hope this helps
