SUMMARY:Open EFTs: assessing the quantum information properties of inflati
 onary models - Thomas Colas (Saclay)

DESCRIPTION:Nearly scale-invariant\, Gaussian and adiabatic scalar perturb
 ations from quantum mechanical origin have been extensively tested using C
 MB and LSS data. Effective Field Theories (EFTs) aim at providing a system
 atic way to consider extensions\, incorporating the knowledge of unknown p
 hysics in a parametrically controlled manner. In order to grasp the implic
 ations of hidden sectors on the quantum information properties of inflatio
 nary models\, the formalism needs to incorporate non-unitary effects such 
 as dissipation and decoherence. In this talk\, I will present the Open EFT
  program which aims at capturing these effects and exhibit situations wher
 e the quantum dynamics of cosmological inhomogeneities evade what was know
 n so far in the lab.
