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…
