Confinement as crossover
  The order parameter of confinement together with the haaron model of the QCD vacuum is reviewed and it is pointed out that confining forces are generated by the non-renormalizable, invariant Haar-measure vertices of the path integral. A hybrid model is proposed for the description of the crossover leading to the confining vacuum. This scenario suggests that the differences between the low and the high temperature phases of QCD should be looked for in the quark channels instead of the hadronic sector.
