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…
Fractal initial conditions and natural parameter values in hybrid inflation
Sebastien Clesse, Christophe Ringeval, Jonathan Rocher
We show that the initial field values required to produce inflation in the two fields original hybrid model, and its supergravity F-term extension, do not suffer from any fine-tuni…
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…
Probing inflation with CMB polarization : weak lensing effect on the covariance of CMB spectra
Jonathan Rocher, Karim Benabed, Francois Bouchet
CMB anisotropies are modified by the weak lensing effect of intervening large scale structures on the photon path from the last scattering surface to the observer. This has to be a…
D-term inflation in non-minimal supergravity
Jonathan Rocher, Mairi Sakellariadou
D-term inflation is one of the most interesting and versatile models of inflation. It is possible to implement naturally D-term inflation within high energy physics, as for example…
