The paper derives an analytical expression for the random close packing density of polydisperse hard disks in 2D, which grows from 0.886 to about 0.98 with size polydispersity and matches a recent simulation at moderate polydispersity.

Analytical solution for the polydisperse random close packing problem in 2D
The paper derives an analytical expression for the random close packing density of polydisperse hard disks in 2D, which grows from 0.886 to about 0.98 with size polydispersity and matches a recent simulation at moderate polydispersity.
