geoSCET: Soft Theorems from Power Counting
Timothy Cohen, Patrick Hager, Andreas Helset
The paper develops a Soft Collinear Effective Theory for a geometric scalar field (geoSCET) and uses it to derive geometric soft theorems from power‑counting arguments, extending 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…
