Abstract:In the vicinity of the deconfinement transition the behaviour of the interquark potential can be precisely predicted using the Effective String Theory (EST). If the transition is continuous we can combine EST results with a conformal perturbation analysis and reach the degree of precision needed to detect the corrections beyond the Nambu-Gotō approximation in the EST. We discuss in detail this issue in the case of the deconfinement transition of the SU(2) gauge theory in (2 + 1) dimensions (which belongs to th… Show more
