On cosmological observables in a swiss-cheese universe (Conference proceeding)
Valerio Marra
By means of a toy Swiss-cheese cosmological model we will discuss how to set up and carry out in a physically meaningful way the idea of back-reaction, according to which dark ener…
Supersymmetric Leptogenesis and the Gravitino Bound
G. F. Giudice, L. Mether, A. Riotto +1
Supersymmetric thermal leptogenesis with a hierarchical right-handed neutrino mass spectrum requires the mass of the lightest right-handed neutrino to be heavier than about 10^9 Ge…
Latest inflation model constraints from cosmic microwave background measurements
William H. Kinney, Edward W. Kolb, Alessandro Melchiorri +1
In this addendum to Phys.Rev. D74 (2006) 023502, we present an update of cosmological constraints on single-field inflation in light of the Wilkinson Microwave Ansiotropy Probe sat…
On Resumming Inflationary Perturbations beyond One-loop
Antonio Riotto, Martin S. Sloth
It is well known that the correlation functions of a scalar field in a quasi-de Sitter space exhibit at the loop level cumulative infra-red effects proportional to the total number…
