The zero temperature relaxational dynamics of a particle in a short rangecorrelated random potential is addressed. We derive a set of "two-times"mean-field dynamical equations, accounting for a possible mean displacement ofthe particle when subject to an external force. We show first detailed resultsfrom the numerical integration of the above mentionned equations. We mainly payattention to the exponentially decreasing spatial correlations case, for whichsimple analytical arguments provide valuable results about the hessian of theenergy landscape, and we propose a geometrical description of the "mean-fieldaging". Our numerical results and further analytical arguments give access tothe waiting time dependence of the main characteristic time scales.Comment: 22 pages, 7 figures, submitted to European Journal of Physics
