Heavy fields, reduced speeds of sound and decoupling during inflation / Achucarro, Ana (Basque U., Bilbao ; Leiden U.) ; Atal, Vicente (Leiden U.) ; Cespedes, Sebastian (Chile U., Santiago) ; Gong, Jinn-Ouk (CERN) ; Palma, Gonzalo A (Chile U., Santiago) ; Patil, Subodh P (Ecole Polytechnique, CPHT)
We discuss and clarify the validity of effective single field theories of inflation obtained by integrating out heavy degrees of freedom in the regime where adiabatic perturbations propagate with a suppressed speed of sound. We show by construction that it is indeed possible to have inflationary backgrounds where the speed of sound remains suppressed and slow-roll persists for long enough. [...]

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.

On Semi-classical Degravitation and the Cosmological Constant Problems / Patil, Subodh P
In this report, we discuss a candidate mechanism through which one might address the various cosmological constant problems. We first observe that the renormalization of gravitational couplings (induced by integrating out various matter fields) manifests non-local modifications to Einstein's equations as quantum corrected equations of motion. [...]
