I wanted to know if the discussion on Wilson loops and Polyakov loops (and their relationship to confinement and asymptotic freedom) is present in the 3 volumes of Weinberg's QFT books but in some other name or heading.
At least I couldn't naively find these topics in that book.
I was hoping to see some detailed discussion about these non-local physical observables and also may be some model calculations and evaluations of them in some gauge theories. In Eduardo Fradkin's lecture notes there exists an evaluation of the Wilson loop in free Maxwell's theory and that too in a certain limit of large time and large separation and thats the only example of such a calculation that I have seen.
{Aside: I would be grateful if people can also point to other pedagogic/classic/path-breaking papers/references in this topic of Wilson loops. To start off these are four papers that I came across while searching along this direction - arXiv:hep-th/0003055, arXiv:hep-th/9911088, arXiv:hep-ph/0905.2317, arXiv:hep-th/9803002}
