The main goal of this report is to derive the macropotential of dust particles interaction in plasmas taking into account both the collective events and polarization phenomena. This reveals a new possible attraction mechanism between grains which results in the crystalline like structure formation of dust particles. The consideration is made using the renormalization theory treating the screening phenomena at large distances. Dust particles are assumed to be immersed in a buffer plasma of electrons and ions which interact with each other via the Coulomb potential. The polarization phenomena are treated via the electrostatic image approximation under the assumption that dust particles are conducting spherical balls. The detailed comparison is provided with the Debye-Huckel theory corresponding to the interaction of pointlike charges immersed in a buffer plasma.References
