Investigating vector boson scattering: A fully gauge-invariant study
Bernd Riederer, Axel Maas
Vector boson scattering (VBS) plays a central role in the search for new physics at collider experiments such as ATLAS and CMS at the LHC. Usually predictions for this kind of proc…
The quenched SU(2) scalar-gluon vertex in minimal Landau gauge
Axel Maas
The question of whether confining effects are visible in correlation functions is a long-standing one. Complementing investigations on the propagators of fundamental and adjoint sc…
Gauge engineering and propagators
Axel Maas
Beyond perturbation theory gauge-fixing becomes more involved due to the Gribov-Singer ambiguity: The appearance of additional gauge copies requires to define a procedure how to ha…
Predicting the singlet vector channel in a partially Higgsed gauge theory
A. Maas, P. Törek
We study a toy version of a grand-unified theory on the lattice: An gauge theory, which experiences a Brout-Englert-Higgs effect due to a single Higgs field in the fundamen…
