geoSCET: Soft Theorems from Power Counting

Timothy Cohen, Patrick Hager, Andreas Helset

We apply the framework of Soft Collinear Effective Theory (SCET) to the theory of the geometric scalar field. The resulting ``geoSCET'' manifests an emergent geometry in the soft s…

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…

Super-Leading Logarithms in Jets

Thomas Becher, Patrick Hager, Giuliano Martinelli +3

Jet observables at hadron colliders feature ''super-leading'' logarithms, double-logarithmic corrections resulting from a breakdown of color coherence due to complex phases in hard…

Factorization restoration through Glauber gluons

Thomas Becher, Patrick Hager, Sebastian Jaskiewicz +2

We analyze the low-energy dynamics of gap-between-jets cross sections at hadron colliders, for which phase factors in the hard amplitudes spoil collinear cancellations and lead to…

Resummation of Glauber Phases in Non-Global LHC Observables for Large

Philipp Böer, Patrick Hager, Matthias Neubert +2

The Glauber series for non-global jet observables at hadron colliders simultaneously includes the super-leading logarithms alongside an arbitrary number of Glauber phases. Building…

Renormalization-Group Improved Resummation of Super-Leading Logarithms

Philipp Böer, Patrick Hager, Matthias Neubert +2

A new strategy is presented for systematically treating super-leading logarithmic contributions including higher-order Glauber exchanges for non-global LHC observables in renormali…

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…

Glauber Phases in Non-Global LHC Observables: Resummation for Gluon-Initiated Processes

Philipp Böer, Patrick Hager, Matthias Neubert +2

The resummation of the ''Glauber series'' in non-global LHC observables is extended to processes with gluons in the initial state. This series simultaneously incorporates large dou…
