“…To the best of our knowledge, the microscopic modeling of this kind of merging is performed here for the first time. All previous theories, see, e.g., [1,2,3,4,10,12,13], deal with the densities of the particles and hence do not take into account the corpuscular structure of the system. However, we do not take into account the particle mass, which is supposed to be done in an extension of the present model.…”
