On the Impact of Flavour Oscillations in Leptogenesis
Andrea De Simone, Antonio Riotto
When lepton flavour effects in thermal leptogenesis are active, they introduce important differences with respect to the case in which they are neglected, the so-called one-flavour…
Leptogenesis and Low Energy CP Violation in Neutrino Physics
S. Pascoli, S. T. Petcov, Antonio Riotto
Taking into account the recent progress in the understanding of the lepton flavour effects in leptogenesis, we investigate in detail the possibility that the CP-violation necessary…
CMB Anisotropies at Second-Order II: Analytical Approach
Nicola Bartolo, Sabino Matarrese, Antonio Riotto
We provide an analytical approach to the second-order Cosmic Microwave Background (CMB) anisotropies generated by the non-linear dynamics taking place at last scattering. We study…
Connecting Low Energy Leptonic CP-violation to Leptogenesis
S. Pascoli, S. T. Petcov, A. Riotto
It was commonly thought that the observation of low energy leptonic CP-violating phases would not automatically imply the existence of a baryon asymmetry in the leptogenesis scenar…
Flavour-Dependent Leptogenesis with Sequential Dominance
S. Antusch, S. F. King, A. Riotto
We study thermal leptogenesis in classes of neutrino mass models based on the seesaw mechanism with three right-handed neutrinos and sequential right-handed neutrino dominance. The…
Inflation model constraints from the Wilkinson Microwave Anisotropy Probe three-year data
William H. Kinney, Edward W. Kolb, Alessandro Melchiorri +1
We extract parameters relevant for distinguishing among single-field inflation models from the Wilkinson Microwave Anisotropy Probe (WMAP) three-year data set, and also from WMAP i…
