N2 - We argue that the statistical weight function W[ρ] appearing in the McLerran-Venugopalan model of a large nucleus is intrinsically non-Gaussian, even if we neglect quantum corrections. Based on the picture where the nucleus of radius R consists of a collection of color-neutral nucleons, each of radius a≪R, we show that to leading order in αs and a/R only the Gaussian part of W[ρ] enters into the final expression for the gluon number density. Thus, the existing results in the literature which assume a Gaussian weight remain valid.
