On the analytic continuation and asymptotic behaviour of the two-point function in massless -theory in Euclidean de Sitter space
Martin Beneke, Andrea F. Sanfilippo
For the two-point function of the massless, minimally-coupled, real scalar field in Euclidean de Sitter space with -interaction, we compute the leading-logarithmic terms in t…
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…
