heal.abstract	The purpose of this paper is to perform a quantitative check of gauge theory-gravity duality in a nonconformal, nonsupersymmetric context. In order to do so we define k5, an object extracted from the Wilson loop, that plays the role of Coulomb's constant for SU(N) gauge theories in five dimensions, and we argue that one of its virtues is that it could be minimally sensitive to N. This allows us to compute k5 on one hand from the gravitational backreation of a large number N of D4-branes, and on the other from a lattice mean-field expansion for N=2. We find a 2% numerical agreement between the two approaches. © 2012 American Physical Society.	en
