Unitarity, BRST Symmetry and Ward Identities in Orbifold Gauge Theories
Thorsten Ohl, Christian Schwinn
We discuss the use of BRST symmetry and the resulting Ward identities for orbifold gauge theories as consistency checks in an arbitrary number of dimensions. We verify that both th…

Gauge checks, consistency of approximation schemes and numerical evaluation of realistic scattering amplitudes
Christian Schwinn
We discuss both theoretical tools to verify gauge invariance in numerical calculations of cross sections and the consistency of approximation schemes used in realistic calculations…

Forests, Groves and Higgs Bosons: Gauge Invariance Classes in Spontaneously Broken Gauge Theories
T. Ohl, C. Schwinn
We determine the gauge invariance classes of tree level Feynman diagrams in spontaneously broken gauge theories, providing a proof for the formalism of gauge and flavor flips. We f…
