The renormalisation group approach is applied to the study of the short-time critical behaviour of the d-dimensional Ginz burg-Landau model with long-range interaction of the form in momentum space. Firstly the system is quenched from a high temperature to the critical temperature and then relaxes to equilibrium within the model A dynamics. The asymptotic scaling laws and the initial slip exponents and θ of the order parameter and the response function respectively, are calculated to the second order in .
