NNLO QCD corrections to from Local Unitarity combined with Coulomb resummation and NLO EW effects
Zeno Capatti, Mathijs Fraaije, Valentin Hirschi +3
The Local Unitarity (LU) formalism provides a constructive, integrand-level realisation of the Kinoshita-Lee-Nauenberg (KLN) theorem, by combining loop and phase-space integrals ap…
Classical worldlines from scattering amplitudes
Zeno Capatti, Mao Zeng
We present a systematic diagrammatic investigation of the classical limit of observables computed from scattering amplitudes in quantum field theory through the Kosower-Maybee-O'Co…
Multi-partonic interactions, iterated discontinuities and the virtuality expansion in deep inelastic scattering
Zeno Capatti, Lucien Huber, Michael Ruf
We introduce a perturbative model that accounts for the contribution of multi-partonic interactions to collider observables. A key feature of this multi-parton model is that cross…
Universal corrections to the superfluid gap in a cold Fermi gas
Silas R. Beane, Zeno Capatti, Roland C. Farrell
A framework for computing the superfluid gap in an effective field theory (EFT) of fermions interacting via momentum-independent contact forces is developed. The leading universal…
