Profiles of the broken string in two-flavor QCD below and above the finite temperature transition
Abstract
We study the Abelian flux tube profile of mesonic and the baryonic configurations of static quarks below and above the finite-temperature transition in Nf=2 full QCD. To reduce effects of ultra-violet fluctuations we measure Abelian distributions of the action density, the color-electric field and the monopole current after fixing to the maximally Abelian gauge. Changing the distance R between quarks for fixed T/Tc<1, one can see a clear signal of string breaking for large R. The electric field becomes Coulomb-like and the circulating monopole current disappears. We study also the temperature dependence of the flux profile for fixed R ≈ 0.7 fm. The disappearance of the squeezed flux is observed clearly above Tc. Similar behaviors are observed both in the mesonic and the baryonic systems.
