Inflation, Strings, CMB anisotropies and Leptogenesis
Rachel Jeannerot
In this talk, I shall focus on theories beyond the Standard Model which predict massive neutrinos. Hybrid inflation emerges naturally in these theories: the slow-rolling inflaton f…
Leptogenesis in Smooth Hybrid Inflation
R. Jeannerot, S. Khalil, G. Lazarides
We present a concrete supersymmetric grand unified model based on the Pati-Salam gauge group SU(4)_c x SU(2)_L x SU(2)_R and leading naturally to smooth hybrid inflation, which avo…
Inflation and Monopoles in Supersymmetric SU(4)_c x SU(2)_L x SU(2)_R
R. Jeannerot, S. Khalil, G. Lazarides +1
We show how hybrid inflation can be successfully realized in a supersymmetric model with gauge group G_{PS}= SU(4)_c x SU(2)_L x SU(2)_R. By including a non-renormalizable superpot…
Supersymmetry breaking and loop corrections at the end of inflation
R. Jeannerot, J. Lesgourgues
We show that quantum corrections to the effective potential in supersymmetric hybrid inflation can be calculated all the way from the inflationary period - when the Universe is dom…
New mechanism for leptogenesis
R. Jeannerot
Unified theories containing a gauge symmetry predict heavy Majorana right-handed neutrinos. In such theories, cosmic strings may form at the breaking scale. If t…
Constraining Supersymmetric SO(10) Models Through Cosmology
Rachel Jeannerot, Anne-Christine Davis
We study the impact of the symmetry breaking patterns from supersymmetric SO(10) down to the standard model on the standard big-bang cosmology through the formation of topological…
