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…
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…
A Quantum Field Theoretical Representation of Euler-Zagier Sums
Uwe Muller, Christian Schubert
We establish a novel representation of arbitrary Euler-Zagier sums in terms of weighted vacuum graphs. This representation uses a toy quantum field theory with infinitely many prop…
A Closed Formula for the Riemann Normal Coordinate Expansion
Uwe Mueller, Christian Schubert, Anton van de Ven
We derive an integral representation which encodes all coefficients of the Riemann normal coordinate expansion, and also a closed formula for those coefficients.
Basis Invariants in Non--Abelian Gauge Theories
Uwe Müller
A basis of Lorentz and gauge-invariant monomials in non--Abelian gauge theories with matter is described, applicable for the inverse mass expansion of effective actions. An algorit…
