Résumé : Fermions scattering off first-order phase transition bubbles, in the framework of SU(2)L ⊗ SU(2)R ⊗ U(1) models, may generate the Baryon Assymetry of the Universe (BAU), either at the LR-symmetry-breaking scale, or at the weak scale. In the latter case, the baryon assymetry of the Universe is related to CP violation in the K0-K0 system. © 1993.
