Yang-Mills Theory as a Deformation of Topological Field Theory, Dimensional Reduction and Quark Confinement

抄録

I propose to reformulate the gauge field theory as the perturbative deformation of a novel topological quantum field theory. It is shown that this reformulation leads to quark confinement in QCD_4. Similarly, the fractional charge confinement is also derived in the strong coupling phase of QED_4. As a confinement criterion, we use the area decay of the expectation value of the Wilson loop.
