| contents | The flavor problem and the baryon asymmetry of the universe (BAU) are addressed simultaneously within a supersymmetric preon model. Standard Model fermions are three-body composites of preons confined at Lambda_cr ~ 10^14 GeV by a Maxwell-Chern-Simons interaction and a metacolor gauge symmetry SU(3)_mc. Gauge anomaly cancellation requires one spectator field chi and no other new fermions. Using four systematic numerical methods validated against the hydrogen atom, we reproduce the observed ratio m_e/m_u = 0.22 at metacolor string tension sigma*_mc/theta^2 = 2.11, and predict m_d > m_u with m_d/m_u ~ 2.3 (observed value of 2.0) from the Pauli principle applied to the psi_0^2 spin-color wavefunction. The neutrino is naturally massless at tree level by the same Pauli-principle argument; the spectator chi provides a Type I seesaw giving m_nu ~ Lambda_EW^2/Lambda_cr ~ 0.1 eV. The BAU is generated at Lambda_cr via the Callan-Harvey anomaly inflow mechanism: integrating out the massive charged preons induces a topological Chern-Simons term whose coefficient is fixed by the fermion/boson condensation asymmetry epsilon from intrinsic SUSY breaking. Matching the observed eta ~ 8.7x10^{-10} gives epsilon ~ 0.022, consistent with a one-loop origin. R-parity is derived dynamically from the composite structure, making the lightest superpartner absolutely stable. |
