We study the effective field theory of inflation, ie the most general theory describing the
fluctuations around a quasi de Sitter background, in the case of single field models. The scalar …

… p MP that we found necessary to treat generic theories of inflation by the methods of
effective field theory. We see that the nonquadratic terms in L0 that can generate non-Gaussian …

… inflation, and our observables are practically limited to correlators of massless fields, heavier
fields and … description for an open effective field theory of inflation, describing the possibly …

… effective field theory of single clock inflation to include dissipative effects. Working in unitary
gauge we couple a set of composite operators, Oµν..., in the effective … of the ‘trapped inflation’ …

… field theory model of inflation that is renormalizable in the matter sector, with a super-Hubble
inflaton mass and sub-Planckian field … energy completion within a theory of quantum gravity. …

… In this paper we address the second question of whether an effective field theory can
produce detectable effects even if those of order H2/M2 are too small to be observable. We here …

… of single-field inflation with small and sharp step features in the potential (and sound speed)
of the inflaton field, in the context of the Effective Field Theory of Inflation. This approach …

… Abstract: We present a general framework where the effective field theory of single field
inflation is extended by the inclusion of operators with mass dimension 3 and 4 in the unitary …

… , as QCD and supersymmetric field theories have indeed taught us. Coming back to the
theory of inflation, when we describe it in terms of a slow rolling inflationary scalar field, we are …
