We present a theory for the particle-particle correlations in physical clusters for which bonding between particles is determined by a connectivity distance and a permanency time. A generalized Mayer density expansion for the cluster pair correlation function is found, as well as an Ornstein-Zernike like relation. We can rely on this formalism to study clustering in realistic models by applying techniques of liquid state theory.
