On Constraining Electroweak-baryogenesis with Inhomogenous Primordial Nucleosynthesis
Primordial 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 He and/or Li and can be ruled out whenever a fraction f ∼ 3 × 10(100 GeV/T ) of nucleated bubbles of broken-symmetry phase contributes > ∼ 10% of the bary...
متن کاملConstraining CMB-consistent primordial voids with cluster evolution
Using cosmological simulations, we make predictions for the distribution of clusters in a plausible non-gaussianmodel where primordial voids nucleated during inflation act together with scale-invariant adiabatic gaussian fluctuations as seeds for the formation of large-scale structure. The parameters of the void network are constrained by the cosmic microwave background (CMB) fluctuations and b...

متن کاملConstraining Primordial Magnetic Field from CMB Anisotropies at Higher Multipoles
The cosmological magnetic field is one of the important physical quantities which affect strongly the cosmic microwave background (CMB) power spectrum. Recent CMB observations have been extended to higher multipoles l &1000, and they resultantly exhibit an excess power than the standard model prediction in cosmological theory which best fits the Wilkinson Microwave Anisotropy Probe (WMAP) data ...
