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…
Factorization Beyond Coherence
Thomas Becher, Patrick Hager, Matthias Neubert +1
We derive a novel factorization theorem for -jettiness at hadron colliders, which incorporates coherence-violating effects induced by Glauber gluons and several new momentum mod…
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…
Low-energy theory of jet processes and PDF factorization
Thomas Becher, Patrick Hager, Sebastian Jaskiewicz +2
The consistency of collinear factorization violation with PDF factorization has been an outstanding challenge and subject of considerable debate. In this work we demonstrate their…
