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.9 pages, 6 figures; v2: misprints correctedHigh Energy Physics - PhenomenologyHigh Energy Physics - LatticeHigh Energy Physics - TheoryNuclear Theorytext
