“…To compute the physical width of the flux tube, we fit the energy density data in mediator plane with appropriate fit function, F(x⊥). There are many kinds of fitting techniques and functions used in previous studies [3][4][5][6]. We here present the technique and function that is consistent with our middle transverse energy density data.…”

We have determined the width of the flux tube for several temperatures and distances using four different fit functions in order to determine the appropriate function that fits the data of the middle transverse distribution of flux tube with the dynamical fermions. Our results have revealed that only one fitting function cannot determine the width of the flux tube at the given temperatures and distances. We conclude that appropriate fit functions are a four coefficient function where R < 0.8 fm and where Gaussian function is R > 0.8 fm.

“…While such flux tubes have been studied for the ordinary static potential using lattice gauge theory for quite some time (see refs. [33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48]), this is a rather new direction for hybrid static potentials, where first results appeared only recently [49][50][51][52]. In this paper we substantially extend existing work by performing computations for seven hybrid static potential sectors characterized by quantum numbers Λ ( )…”

We compute chromoelectric and chromomagnetic flux densities for hybrid static potentials in SU(2) and SU(3) lattice gauge theory. In addition to the ordinary static potential with quantum numbers Λ η = Σ + g , we present numerical results for seven hybrid static potentials corresponding to Λwhere the flux densities of five of them are studied for the first time in this work. We observe hybrid static potential flux tubes, which are significantly different from that of the ordinary static potential. They are reminiscent of vibrating strings, with localized peaks in the flux densities that can be interpreted as valence gluons. arXiv:1907.01482v2 [hep-lat]

“…The fate of the confining properties is another issue of obvious theoretical and phenomenological interest. Deconfinement is clearly signalled by the suppression of color flux tubes across T c [32,33,34], even if structures similar to flux tubes still seem to form between heavyQQ pairs for temperatures up to ∼ 1.5 T c [34], and have been related to the possible presence of chromomagnetic charges populating the Quark-Gluon Plasma (QGP) [35]. Precise determinations of the heavyQQ potential at higher temperatures have been reported recently [36] (for T up to ∼ 6 GeV), showing that the potential is perturbative at short distances and screened for distances r such that r T 0.3; results on the dependence of color screening on the baryon density have also been reported at this conference [37].…”
