The Spatial String Tension in the Deconfined Phase of SU(N) Gauge Theory and Gauge/String Duality
Abstract
Description
The spatial string tension of a SU(N) gauge theory without quarks is calculated using gauge/string duality for 1.2T_c<T<3T_c. The result is remarkably consistent with the available lattice data for N=2,3. Some evidence is found that to leading order the large distance physics of a string can be described by a five-dimensional geometry without a need for an internal space.
