We study the Abelian flux tube profile of the mesonic and baryonic configurations formed by static quarks below and above the finite-temperature transition in Nf = 2 lattice QCD. To reduce the effects of ultra-violet fluctuations, we measure Abelian distributions of the action density, the color-electric field and the monopole current in the maximally Abelian projection. For fixed temperature, T (with T/Tc ≪ 1), we observe a clear signal of the string breaking for a large test quark separation R. The electric field becomes Coulomb-like and the circulating monopole current disappears. We also study the temperature dependence of the flux profile for fixed R ≈ 0.7 fm. The squeezed flux disappears above Tc.
