Nucleosynthesis Constraints on Defect-Mediated Electroweak Baryogenesis

In the defect-mediated electroweak baryogenesis scenario, baryons are produced in well separated regions of space. It is shown that between the electroweak phase transition at a temperature of $T\sim 100\mathrm{G}\mathrm{e}\mathrm{V}$ and the end of nucleosynthesis at $T\sim 1\mathrm{K}\mathrm{e}\mathrm{V}$ the baryon inhomogeneities dissipate, and that no constraints on defect-mediated electroweak baryogenesis can be derived from considerations of inhomogeneous nucleosynthesis.
