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…
Supersymmetric Q-balls: A Numerical Study
L. Campanelli, M. Ruggieri
We study numerically a class of non-topological solitons, the Q-balls, arising in supersymmetric extension of the Standard Model with low-energy, gauge-mediated symmetry breaking.…
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…
Cosmic Microwave Background Quadrupole and Ellipsoidal Universe
L. Campanelli, P. Cea, L. Tedesco
Recent Wilkinson Microwave Anisotropy Probe (WMAP) data confirm the Cosmic Microwave Background (CMB) quadrupole anomaly. We further elaborate our previous proposal that the quadru…
