Abstract: (arXiv)
In the color glass condensate framework the saturation scale measured in deep inelastic scattering of high energy hadrons and nuclei can be determined from the correlator of Wilson lines in the hadron wavefunction. These same Wilson lines give the initial condition of the classical field computation of the initial gluon multiplicity and energy density in a heavy ion collision. In this paper the Wilson line correlator in both adjoint and fundamental representations is computed using exactly the same numerical procedure that has been used to calculate gluon production in a heavy ion collision. This fixes the logarithmic uncertainty in the relation between the color charge density parameter g^2\mu and the saturation scale Qs as Qs = 0.6 g^2\mu. The resulting classical Yang-Mills value for the 'gluon liberation coefficient' is c = 1.1.- 24.85.+p
