It is shown that the dust density regimes in dusty plasma are characterized by two complementary screening processes, (a) low regime where Debye dominant process and (b) high Coulomb process. The a state all particles carry an equal constant charge. high-density or charge depends on spatial location screened other vicinity reduction, quark like asymptotic freedom particles, which average minimal electric (q tends to 0), asymptotically free, (c) uniform potential, (d) neutralization background of hot ions. Thus, essentially one-component (OCP) with as opposed electron OCP without screening. Molecular dynamics (MD) simulations verify these properties. MD performed, using recently developed Hamiltonian formalism, study Yukawa carrying variable A hydrodynamic model for describing collective properties its characteristic acoustic mode called wave given.
