Namely, given two functions ρ<sub>1</sub>(i) and ρ<sub>2</sub>(i,j) non-negative and symmetric on Z<sup>d</sup>, we ask whether they are the first two correlation functions of a translation invariant point process. We provide an explicit construction of such a realizing process for any d ≥ 2 when the radial distribution has a specific form. We also derive from this construction a lower bound for the maximal realizable density and compare it with the already known lower bounds. 2017-08-17T12:57:12Z
