A kinetic theory of cluster formation is developed based on the recent numerical results of N-body systems. First, a stability criterion for equilibrium clusters is formulated in terms of residence time distributions. Secondly, the Negative-Weibull distribution is derived theoretically in a certain scaling hypothesis under a free particle approximation. Thirdly, the origin of the Universal Long Tail is explained from a general feature of nearly integrable hamiltonian dynamics. Lastly, the collapse of unstable cluster is briefly discussed.
