DESCRIPTION:We consider a mean field type equation for ballistic aggregati
 on of particles whose density function depends both on the mass and impuls
 ion of the particles. For the case of a constant aggregation rate the exis
 tence of self-similar solutions and the convergence of more general soluti
 ons to them is proven.The large time decay of some moments of general solu
 tions is estimated. Some new classes of self-similar solutions for several
  classes of mass and/or impulsion dependent rates are obtained.
