Abstract: (Elsevier)

In hot QCD matter with a colour confining-non-confining first order phase transition at T c , the two phases can coexist at T c with a stable interface in between. We show how the structure of this interface and its tension α can be determined with lattice MonteCarlo methods. On an N t = 2 lattice with an 8 × 8 × 40 spatial size the result is α / T c 3 = 0.24 ± 0.06, the interface extends over more than 2 fm.
