Spatial 't Hooft Loop to Cubic Order in Hot Qcd

Spatial 't Hooft loops of strength k measure the qualitative change in the behaviour of electric colour flux in confined and deconfined phase of SU(N) gauge theory. They show an area law in the deconfined phase, known analytically to two loop order with a " k-scaling " law k(N − k). In this paper we compute the O(g 3) correction to the tension. It is due to… (More)
