  In search of a phenomenological model that would describe physics from Big
Bang to the Standard Model (SM), we propose a model with the following
properties (i) above an energy about Lambda_{cr} > 10^{16} GeV there are
Wess-Zumino supersymmetric preons and Chern-Simons (CS) fields, (ii) at
Lambda_{cr} ~ 10^{16} GeV spontaneous gauge symmetry breaking takes place in
the CS model and the generated topological mass providing attractive
interaction to equal charge preons, and (iii) well below 10^{16} GeV the model
reduces to the standard model with essentially pointlike quarks and leptons,
having a radius ~ 10^{-31} m. The baryon asymmetry turns out to have a
fortuitous ratio n_B/n_gamma << 1.
