“…The squeezed flux-tube, by virtue of the surrounding superconductiong medium [2,3,13], is conjectured to vibrate, after roughening, like a massless string. The profile of the vibrating flux tube can be unraveled in numerical lattice simulations by correlating the field strength of the QCD vacuum to the constructed quark states [14][15][16][17]. The large distance properties of the energy distribution in the meson have been a subject of many lattice simulations targeting the properties of the flux tubes at both zero and finite temperatures.…”

We look into the signatures of the effective Y-bosonic strings in the gluonic profile due to a system of three static quarks on the lattice. The gluonic distribution is calculated in pure YangMills lattice gauge theory at finite temperature with Polyakov loops operators. The analysis of the action density unveils a filled-∆ distribution. However, we found that these ∆-shaped action density profiles are structured from three Y-shaped Gaussian-like flux-tubes. The length of the revealed Yflux system increases with the increasing of the color source separation and reaches maximum near the deconfinement point. The lattice data for the mean-square width of the gluonic action density have been compared to the corresponding width calculated based on the string model at finite temperature. We assume Y-string configuration with minimal length. The growth pattern of the action density of the gluonic field fits well to junction fluctuations of the Y-baryonic string model for large quark separation at the considered temperatures.

“…Early lattice gauge theory attempts to compute the colour field distribution, without recourse to modelling, were necessarily limited by the available compute power and lattice methods of the period. They rendered qualitative rather than quantitative results, with lattice resolutions, a, and quark-antiquark separations, r, restrained to a > .15 fm and r = aR < 1 fm, respectively [2,3,4,5].…”

We present results of a high statistics study of the chromo field distribution between static quarks in SU(2) gauge theory on lattices of volumes 16 4 , 32 4 , and 48 3 × 64, with physical extent ranging from 1.3 fm up to 2.7 fm at β = 2.5, β = 2.635, and β = 2.74. We establish string formation over physical distances as large as 2 fm. The results are tested against Michael's sum rules. A detailed investigation of the transverse action and energy flux tube profiles is provided. As a by-product, we obtain the static lattice potential in unpreceded accuracy.

“…The qualitative description of these density plots suggests a two-dimensional Gaussian-like behavior; however, as we will see in the next section, careful measurements of the widths at each perpendicular plane to the q " q line yield different widths for large distances. The behavior of the flux distribution around the outer edges of the density profile does depend on finite volume [36]. As a by-product of performing the simulations on large lattice sizes to gain high statistics in a gaugeindependent manner, the two lattices employed in these investigations are of a typical spatial size of 3:6 3 fm 3 which does minimize the volume effect.…”

The simulations are performed in quenched QCD for two temperatures below the deconfinement phase. Unlike the gluonic profiles displayed at T ¼ 0, the action-density isosurfaces display a prolate-spheroid-like shape. The curved width profile of the flux tube is found to be consistent with the prediction of the free bosonic string model at large distances.
