QCD, confinement.

  1. Oct 25, 2007 #1
    Which is the connection between the perimeter law for Wilson loops and quantum fluctuations of matter fields (presenting in the QCD Lagrangian); and why quantum fluctuations of gauge (Yang-Mills, gluonic) fields infolve the area law for appropriate Wilson loops? Senk You. Leonid.

    Garmonic potential

    Can the "garmonic" ("squared") potential V\sim r^2 supply the correct infrared behaviour necessary for confinement (i.e. the q^(-\alpha), \alpha>0 as q\to 0 in the momentum space)?
    Sincerely, Leonid.

    QCD, FP ghosts

    Why (Faddeev-Popov) ghosts are absent in the axial gauge A_3=0?
    Sincerelly, Leonid.

    because ghost does not couple to gauge field in axial gauge

    vertices in the path integral formalism

    The origin of the ln det G item (where G(\phi) is the Green function in the \lambda \phi^4 model, for instance)?
    Sincerelly, Leonid.
