Classical conformal invariance and superhorizon dynamics in de Sitter
Maria Cristina Fiore, Andrea F. Sanfilippo
Soft de Sitter Effective Theory is a well-motivated candidate for the correct effective late-time description of equal-time correlation functions in de Sitter space. In this work,…
Quantum correction to the diffusion term in stochastic inflation from composite-operator matching in Soft de Sitter Effective Theory
Martin Beneke, Patrick Hager, Andrea F. Sanfilippo
In the framework of Soft de Sitter Effective Theory (SdSET), the Fokker-Planck equation for the late-time dynamics of the massless minimally coupled scalar field and its extension…
Renormalisation and matching of massless scalar correlation functions in Soft de Sitter Effective Theory
Martin Beneke, Patrick Hager, Andrea F. Sanfilippo
For light and massless scalar fields, cosmological correlation functions suffer from infrared divergences and secular logarithms. Soft de Sitter Effective Theory (SdSET) has been p…
Cosmological Correlators in massless -theory and the Method of Regions
Martin Beneke, Patrick Hager, Andrea F. Sanfilippo
The calculation of loop corrections to the correlation functions of quantum fields during inflation or in the de~Sitter background presents greater challenges than in flat space du…
Double copy for Lagrangians at trilinear order
M. Beneke, P. Hager, A. F. Sanfilippo
We present a novel double-copy prescription for gauge fields at the Lagrangian level and apply it to the original double copy, couplings to matter and the soft theorem. The Yang-Mi…
