Summing Feynman diagrams in the worldline formalism
Naser Ahmadiniaz, James P. Edwards, Cristhiam Lopez-Arcos +4
The worldline formalism shares with string theory the property that it allows one to write down master integrals that effectively combine the contributions of many Feynman diagrams…
Generalized Gelfand-Dikii equation for fermionic Schwinger pair production
Naser Ahmadiniaz, Sang Pyo Kim, Christian Schubert
Schwinger pair creation in a purely time-dependent electric field can be reduced to an effective quantum mechanical problem using a variety of formalisms. Here we develop an approa…
Generalized Gelfand-Dikii equation and solitonic electric fields for fermionic Schwinger pair production
Naser Ahmadiniaz, Alexander M. Fedotov, Evgeny G. Gelfer +2
In previous work on Schwinger pair creation in purely time-dependent fields, it was shown how to construct ``solitonic'' electric fields that do not create scalar pairs with an arb…
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…
Generalized LKF transformations for -point fermion correlators in QED
José Nicasio, Christian Schubert, Naser Ahmadiniaz +1
Within the worldline approach to quantum electrodynamics (QED), a change of the photon's covariant gauge parameter is investigated to analyse the non-perturbative gauge depende…
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…
