Effective theories of single field inflation when heavy fields matter / Achucarro, Ana (Leiden U. ; Basque U., Bilbao) ; Gong, Jinn-Ouk (CERN) ; Hardeman, Sjoerd (Leiden U.) ; Palma, Gonzalo A (Chile U., Beaucheff) ; Patil, Subodh P (Ec. Polytech., Palaiseau (main) ; Ecole Normale Superieure)
We compute the low energy effective field theory (EFT) expansion for single-field inflationary models that descend from a parent theory containing multiple other scalar fields. By assuming that all other degrees of freedom in the parent theory are sufficiently massive relative to the inflaton, it is possible to derive an EFT valid to arbitrary order in perturbations, provided certain generalized adiabaticity conditions are respected.

Mass hierarchies and non-decoupling in multi-scalar field dynamics / Achúcarro, Ana ; Gong, Jinn-Ouk ; Hardeman, Sjoerd ; Palma, Gonzalo A ; Patil, Subodh P
In this work we study the effects of field space curvature on scalar field perturbations around an arbitrary background field trajectory evolving in time. Non-trivial imprints of the `heavy' directions arise when the vacuum manifold of the potential does not coincide with the span of geodesics defined by the sigma model metric of the low energy effective theory.
