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…
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…
