Confining string formed by P-vortices in the indirect Z(2) projection of SU(2) lattice gauge theory
PACS: 11.15.Ha, 11.25.Sq
Abstract
We study the distribution of P-vortices near the confining string in the indirect Z(2) projection of SU(2) lattice gauge theory. We find that the density of vortices approaches the vacuum value at large distances and is strongly suppressed near the line connecting the test quark-antiquark pair. This implies that the condensate of P-vortices is broken inside the confining string. The width of the P-vortex density distribution increases with increasing distance between the quark and antiquark. Our best fit indicates the logarithmic dependence of this width on q\bar{q} separation distance.
