The feasibility of B-violation during a first-order phase transition quark-gluon plasma (QGP) – hadronic gas (HG) in a hot Universe is considered. The conditions for the attainability of B-asymmetry 10 -8 – 10 -5 (at Ωb ~ 1) are analyzed, due to antiquark–quark transitions of the type νμ + d̃ → u + μ- (ΔB ≠ 0) with C-violation in the QGP with the participation of muon neutrinos after separation of the heavy antileptons that give birth to them, from the leptons polarized during scattering on the walls of the growing HG bubbles. Thus, heavy leptons and antileptons can acquire opposite spin orientation at birth (P-violation). Quark oscillations in AG hadrons occur without B-violation (ΔB = 0). The contribution of neutrinos and τ-leptons to the B-asymmetry realized during the decay of the QGP of nuclear density is argued by their high penetrating ability and participation in weak interactions, which are characterized by CP-violation.
