The setting sun diagram with complex external momenta
David Dudal, Duifje Maria van Egmond, Gastao Krein
We revisit the issue of analytically continuing Feynman integrals from Euclidean to Minkowski signature, allowing for generic complex momenta. Although this is well-known in terms…
Center-symmetric Landau gauge, the deconfinement transition and the gluon propagator as seen in lattice QCD
Duifje Maria van Egmond, Orlando Oliveira, Urko Reinosa +3
We address the lattice computation of the gluon propagator in the center-symmetric Landau gauge. After discussing a proper lattice implementation of the center-symmetric Landau gau…
The center-symmetric Landau gauge meets the lattice
Duifje Maria van Egmond, Orlando Oliveira, Urko Reinosa +3
A lattice implementation of the recently introduced center-symmetric Landau gauge is discussed and its predictions confronted with numerical Monte Carlo simulations. It is shown th…
Subleading Higgs effects at lepton colliders
Axel Maas, Duifje M. van Egmond, Simon Plätzer
Subtle field-theoretical effects suggest the presence of additional Higgs contributions in standard model processes. This has been supported by electroweak lattice calculation, e.\…
