String breaking and monopoles
arXiv:hep-lat/0211026
Abstract
The string breaking is discussed in U(1)^{N-1} Abelian effective theories of QCD. When a screening is expected, the static potential shows a flattening in the long-range region and a linear behavior in the intermediate region. We show why the screening is better observed in the Polyakov-loop correlators than in the Wilson loops. The breaking of the adjoint string is explained without the Z(N) picture.
