标题： Confining string and P-vortices in the indirect Z(2) projection of SU(2) lattice gauge theory

摘要： 我们研究了在SU(2)格点规范理论的间接Z(2)投影中，紧致弦附近P旋涡的分布。 在远距离处，旋涡的密度是恒定的，并且在连接测试夸克-反夸克对的线附近强烈抑制。 这意味着紧致弦内部P旋涡的凝聚被破坏。 我们还发现，P旋涡密度分布的宽度与夸克和反夸克之间距离的对数成正比。 显示英文摘要

摘要： We study the distribution of P-vortices near the confining string in the indirect Z(2) projection of SU(2) lattice gauge theory. It occurs that the density of vortices is constant at large distances and strongly suppressed near the line connecting the test quark-antiquark pair. This means that the condensate of P-vortices is broken inside the confining string. We also find that the width of the P-vortex density distribution is proportional to the logarithm of the distance between the quark and antiquark.
