Abstract
We calculate the dynamics of local and non-local correlation functions of a three dimensional weakly interacting Bose gas after an interaction quench. Within the Bogoliubov approximation we discuss the resulting quasisteady prethermal state and relaxation to it. We finally discuss the decay rates of Bogoliubov quasi-particles characterizing the expected departure from the prethermal state towards a fully thermalized one.
