On constraining electroweak-baryogenesis with inhomogeneous primordial nucleosynthesis

Abstract Primodial nucleosynthesis calculations are shown to be able to provide constraints on models of electroweak baryogenesis which produce a highly inhomogeneous distribution of the baryon-to-photon ratio. Such baryogenesis scenarios overproduce 4 He and/or 7 Li and can be ruled out henever a fraction f ≲3×10 −6 (100GeV/ T ) 3 of nucleated bubbles of broken-symmetry phase contributes ≳10% of the baryon number within a horizon volume.
