Abstract
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.
