Particle physics models of inflation and curvaton scenarios
Anupam Mazumdar, Jonathan Rocher
We review the particle theory origin of inflation and curvaton mechanisms for generating large scale structures and the observed temperature anisotropy in the cosmic microwave back…
Scalar Multiplet Dark Matter
T. Hambye, F. -S. Ling, L. Lopez Honorez +1
We perform a systematic study of the phenomenology associated to models where the dark matter consists in the neutral component of a scalar SU(2)_L n-uplet, up to n=7. If one inclu…
Avoiding the blue spectrum and the fine-tuning of initial conditions in hybrid inflation
Sebastien Clesse, Jonathan Rocher
Hybrid inflation faces two well-known problems: the blue spectrum of the non-supersymmetric version of the model and the fine-tuning of the initial conditions of the fields leading…
Constraining SUSY GUTs and Inflation with Cosmology
Jonathan Rocher
In the framework of Supersymmetric Grand Unified Theories (SUSY GUTs), the universe undergoes a cascade of symmetry breakings, during which topological defects can be formed. We ad…
-term inflation, cosmic strings, and consistency with cosmic microwave background measurement
Jonathan Rocher, Mairi Sakellariadou
Standard D-term inflation is studied in the framework of supergravity. D-term inflation produces cosmic strings, however it can still be compatible with CMB measurements without in…
Constraining SUSY GUTS with Cosmology
Mairi Sakellariadou, Jonathan Rocher
Cosmic strings of the GUT scale, generically formed during the SSB of supersymmetric hybrid inflation, are compatible with the most recent CMB data. The strong constraints on the a…
