Lepton-Pair Scattering With an Off-Shell and an On-Shell Photon at Two Loops in Massless QED
Simone Zoia
I present the computation of the two-loop amplitudes for the scattering of a lepton pair with an off-shell and an on-shell photon in massless QED. We apply modern techniques develo…
Learning Feynman integrals from differential equations with neural networks
Francesco Calisto, Ryan Moodie, Simone Zoia
We perform an exploratory study of a new approach for evaluating Feynman integrals numerically. We apply the recently-proposed framework of physics-informed deep learning to train…
Lepton-pair scattering with an off-shell and an on-shell photon at two loops in massless QED
Simon Badger, Jakub Kryś, Ryan Moodie +1
We compute the two-loop QED helicity amplitudes for the scattering of a lepton pair with an off-shell and an on-shell photon, , using the approximation of mas…
Isolated photon production in association with a jet pair through next-to-next-to-leading order in QCD
Simon Badger, Michal Czakon, Heribertus Bayu Hartanto +4
In this work, we provide a comprehensive set of differential cross-section distributions for photon + di-jet production in proton-proton collisions with next-to-next-to-leading ord…
Two-loop amplitudes in massless QCD for diphoton-plus-jet production via gluon fusion at hadron colliders
Ryan Moodie
The ability to calculate analytic full-colour two-to-three two-loop helicity amplitudes in massless QCD has been a recent triumph of the field, driving phenomenology towards one pe…
Precision QCD corrections to gluon-initiated diphoton-plus-jet production at the LHC
Ryan Moodie
In this thesis, we present recent advances at the precision frontier of higher-order quantum chromodynamics (QCD) calculations. We consider massless two-loop five-point amplitudes,…
Optimising hadronic collider simulations using amplitude neural networks
Ryan Moodie
Precision phenomenological studies of high-multiplicity scattering processes at collider experiments present a substantial theoretical challenge and are vitally important ingredien…
Next-to-leading order QCD corrections to diphoton-plus-jet production through gluon fusion at the LHC
Simon Badger, Thomas Gehrmann, Matteo Marcoli +1
We compute the next-to-leading order (NLO) QCD corrections to the gluon-fusion subprocess of diphoton-plus-jet production at the LHC. We compute fully differential distributions by…
Optimising simulations for diphoton production at hadron colliders using amplitude neural networks
Joseph Aylett-Bullock, Simon Badger, Ryan Moodie
Machine learning technology has the potential to dramatically optimise event generation and simulations. We continue to investigate the use of neural networks to approximate matrix…
Virtual QCD corrections to gluon-initiated diphoton plus jet production at hadron colliders
Simon Badger, Christian Brønnum-Hansen, Dmitry Chicherin +7
We present an analytic computation of the gluon-initiated contribution to diphoton plus jet production at hadron colliders up to two loops in QCD. We reconstruct the analytic form…
Generalized classes of continuous symmetries in two-mode Dicke models
Ryan I. Moodie, Kyle E. Ballantine, Jonathan Keeling
As recently realized experimentally [Léonard et al., Nature 543, 87 (2017)], one can engineer models with continuous symmetries by coupling two cavity modes to trapped atoms, via a…
Polarization dynamics in a photon BEC
Ryan I. Moodie, Peter Kirton, Jonathan Keeling
It has previously been shown that a dye-filled microcavity can produce a Bose-Einstein condensate of photons. Thermalization of photons is possible via repeated absorption and re-e…
