TL;DR
This paper investigates the structure of confining strings in SU(2) lattice gauge theory, revealing how their width varies with quark-antiquark separation and flux tube reconstruction in multi-quark systems.
Contribution
It provides new insights into the behavior of flux tubes and string widths in lattice gauge theory, especially in multi-quark configurations.
Findings
The confining string width grows logarithmically with quark-antiquark distance.
Flux tube reconstruction occurs when changing the separation between quark-antiquark pairs.
Action and energy densities support the flux tube behavior in the studied systems.
Abstract
We study the action and the energy densities of the confining string in the indirect Z(2) projection of SU(2) lattice gauge theory. We find that the width of the confining string is proportional to the logarithm of the distance between the quark and antiquark. In system we observe the effect of the reconstruction of the flux tube when we change the distance between two pairs.
