Inflation-Produced Magnetic Fields in R^n F^2 and I F^2 models
L. Campanelli, P. Cea, G. L. Fogli +1
We re-analyze the production of seed magnetic fields during Inflation in (R/m^2)^n F_{μν}F^{μν} and I F_{μν}F^{μν} models, where n is a positive integer, R the Ricci scalar, m a ma…
Inflation-Produced Magnetic Fields in Nonlinear Electrodynamics
L. Campanelli, P. Cea, G. L. Fogli +1
We study the generation of primeval magnetic fields during inflation era in nonlinear theories of electrodynamics. Although the intensity of the produced fields strongly depends on…
Baryogenesis and CP-Violating Domain Walls in the Background of a Magnetic Field
Leonardo Campanelli, Paolo Cea, Gian Luigi Fogli +1
Within the domain wall-mediated electroweak baryogenesis, we study fermion scattering off a CP-violating wall in the background of an uniform magnetic field. In particular, we calc…
Constraints on the Sum of Neutrino Masses from Cosmology and their impact on world neutrino data
A. Melchiorri, G. L. Fogli, E. Lisi +4
We derive upper limits on the sum of neutrino masses from an updated combination of data from Cosmic Microwave Background experiments and Galaxy Redshifts Surveys. The results are…
Dynamics of Ferromagnetic Walls: Gravitational Properties
L. Campanelli, P. Cea, G. L. Fogli +1
We discuss a new mechanism which allows domain walls produced during the primordial electroweak phase transition. We show that the effective surface tension of these domain walls c…
Charged Domain Walls
L. Campanelli, P. Cea, G. L. Fogli +1
In this paper we investigate Charged Domain Walls (CDW's), topological defects that acquire surface charge density induced by fermion states localized on the walls. The presenc…
