Abstract— <p>We consider the period of the Universe evolution when quarks were in a free state (10^‒38‒10^‒30 s). Quarks with an electric charge <i>q</i>&#xa0;= ±2/3 and ±2/3 at the input in reactions of scattering on bosons in the supersymmetric period of evolution (10¹⁶‒10¹² GeV) could create both the baryonic and antibaryonic world. Additional reactions with the same gauge (<i>B‒L</i>) also took place at <i>q</i> = ±2/3 and ±1/3. The subsequent confinement of quarks hardened the ratio of u and d quarks in protons and in light nuclei such as deuterons and α-particles. The stirring of quarks in scattering reactions with the formation of leptons led to the fixation of the composition of the main baryonic components as well as to the baryon and lepton asymmetry. The scattering bosons could be deuterons and α-particles.</p>
