On Constraining Electroweak-Baryogenesis with Inhomogeneous Primordial Nucleosynthesis

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