THE CONFINING STRING AND ITS TENSION FOR SU(2) GAUGE-FIELDS IN 2+1 DIMENSIONS

We investigate confinement in D=3 SU(2) lattice gauge theory. We confirm the approximately linear character of confinement at large distances. The corresponding continuum string tension is found to be √σ/g2=0.3340±0.0025. We also find that the flux is located within a tube and that the width of this...
