Distribution of the color fields around static quarks: Flux tube profiles

Abstract

We report detailed calculations of the profiles of energy and action densities in the quark-antiquark string in SU(2) lattice gauge theory. We conclude that at a q-q\ifmmode\bar\else\textasciimacron\fi{} separation R\ensuremath{\approxeq}1.0 fm we are beginning to see the asymptotic flux tube. By employing the Michael sum rules we further conclude that the peak energy density approaches a constant in R. \textcopyright{} 1995 The American Physical Society.
