One-loop Amplitudes in the Worldline Formalism
James P. Edwards, C. Moctezuma Mata, Christian Schubert
We summarize recent progress in applying the worldline formalism to the analytic calculation of one-loop N-point amplitudes. This string-inspired approach is well-adapted to avoidi…
Obtaining fully polarised amplitudes in gauge invariant form
Naser Ahmadiniaz, Victor Miguel Banda Guzman, Christian Schubert +3
We describe progress applying the \textit{Worldline Formalism} of quantum field theory to the fermion propagator dressed by -photons to study multi-linear Compton scattering pro…
Graviton scattering amplitudes in first quantisation
James P. Edwards
We give a pedagogical review to alternative, first quantised approaches to calculating graviton scattering amplitudes, giving an introduction to string inspired approaches and pres…
New Techniques for Worldline Integration
James P. Edwards, C. Moctezuma Mata, Uwe Müller +1
The worldline formalism provides an alternative to Feynman diagrams in the construction of amplitudes and effective actions that shares some of the superior properties of the organ…
N-photon amplitudes in a plane-wave background
James P. Edwards, Christian Schubert
We use the worldline formalism to derive master formulas for the one-loop N-photon amplitudes in a plane-wave background, for both scalar and spinor QED. This generalises previous…
The Generalised LKF Transformations for Arbitrary -point Fermion Correlators
Naser Ahmadiniaz, James P. Edwards, José Nicasio +1
We examine the non-perturbative gauge dependence of arbitrary configuration space fermion correlators in quantum electrodynamics (QED). First, we study the dressed electron propaga…
