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…
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…
