Non-Gaussianities in extended D-term inflation
Francis Bernardeau, Tristan Brunier
We explore extensions of hybrid inflationary models in the context of supersymmetric D-term inflation. We point out that a large variety of inflationary scenarios can be encountere…
Models of inflation with primordial non-Gaussianities
Francis Bernardeau, Tristan Brunier, Jean-Philippe Uzan
We present a class of models in which the primordial metric fluctuations do not necessarily obey Gaussian statistics. These models are realizations of mechanisms in which non-Gauss…
The shape of high order correlation functions in CMB anisotropy maps
T. Brunier, F. Bernardeau
We present a phenomenological investigation of non-Gaussian effects that could be seen on CMB temperature maps. Explicit expressions for the temperature correlation functions are g…
Radiative corrections to scalar masses in de Sitter space
T. Brunier, F. Bernardeau, J. -P. Uzan
We compute the radiative corrections to the mass of a test boson field in an inflating space-time. The calculations are carried out in case of a boson part of a supersymmetric chir…
Two Loop Scalar Self-Mass during Inflation
T. Brunier, V. K. Onemli, R. P. Woodard
We work in the locally de Sitter background of an inflating universe and consider a massless, minimally coupled scalar with a quartic self-interaction. We use dimensional regulariz…
Constraints on mode couplings and modulation of the CMB with WMAP data
Simon Prunet, Jean-Philippe Uzan, Francis Bernardeau +1
We investigate a possible asymmetry in the statistical properties of the cosmic microwave background temperature field and to do so we construct an estimator aiming at detecting a…
