Worldline representation of multiloop amplitudes in quantum electrodynamics
Victor M. Banda Guzmán, Uwe Müller, Cristofer Nava Jacuinde +2
The worldline approach to quantum electrodynamics allows one to construct integral representations combining large numbers of Feynman diagrams. Here I review the state-of-the-art o…
Integration techniques for worldline integrals
Victor M. Banda Guzman, James P. Edwards, C. Moctezuma Mata Zamora +2
The worldline formalism allows one to obtain compact integral representations combining the information of large numbers of Feynman diagrams. However, their analytic calculation le…
Worldline integration of photon amplitudes
Naser Ahmadiniaz, Victor M. Banda Guzmán, James P. Edwards +5
It has been known for many years that methods inspired by string theory, such as the worldline formalism, allow one to write down integral representations that combine large number…
Low-energy limit of N-photon amplitudes in a constant field
Naser Ahmadiniaz, Misha A. Lopez-Lopez, Christian Schubert
While the QED photon amplitudes at full momentum so far have been calculated only up to the six-photon level, in the low-energy limit there are explicit formulas for all helicity c…
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…
Worldline master formulas for the dressed electron propagator, part 2: On-shell amplitudes
Naser Ahmadiniaz, Victor Miguel Banda Guzman, Fiorenzo Bastianelli +3
In the first part of this series, we employed the second-order formalism and the ``symbol'' map to construct a particle path-integral representation of the electron propagator in a…
