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…
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…
On Resonant Leptogenesis
Andrea De Simone, Antonio Riotto
It has been recently shown that the quantum Boltzmann equations may be relevant for the leptogenesis scenario. In particular, they lead to a time-dependent CP asymmetry which depen…
Quantum Boltzmann Equations and Leptogenesis
Andrea De Simone, Antonio Riotto
The closed time-path formalism is a powerful Green's function formulation to describe non-equilibrium phenomena in field theory and it leads to a complete non-equilibrium quantum k…
Observable Electron EDM and Leptogenesis
F. R. Joaquim, I. Masina, A. Riotto
In the context of the minimal supersymmetric seesaw model, the CP-violating neutrino Yukawa couplings might induce an electron EDM. The same interactions may also be responsible fo…
WIMPZILLAS!
Edward W. Kolb, Daniel J. H. Chung, Antonio Riotto
There are many reasons to believe the present mass density of the universe is dominated by a weakly interacting massive particle (WIMP), a fossil relic of the early universe. Theor…
