Dispersion of Ultra-Relativistic Tardyonic and Tachyonic Wave Packets on Cosmic Scales
José Nicasio, Ulrich D. Jentschura
We investigate the time propagation of tachyonic (superluminal) and tardyonic (subluminal, ordinary) massive wave packets on cosmic scales. A normalizable wave packet cannot be mon…
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 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…
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…
Non-perturbative gauge transformations of arbitrary fermion correlation functions in quantum electrodynamics
José Nicasio, James P. Edwards, Christian Schubert +1
We study the transformation of the dressed electron propagator and the general -point functions under a change in the covariant gauge of internal photon propagators. We re-estab…
