Dyson-Schwinger equations and SYM in Landau gauge
Axel Maas, Stefan Zitz
Super Yang-Mills theory is a highly constrained theory, and therefore a valuable tool to test the understanding of less constrained Yang-Mills theories. Our aim is to…
On the effect of time-dependent inhomogeneous magnetic fields in electron-positron pair production
Christian Kohlfürst, Reinhard Alkofer
Electron-positron pair production in space- and time-dependent electromagnetic fields is investigated. Especially, the influence of a time-dependent, inhomogeneous magnetic field o…
Poincare covariant pseudoscalar and scalar meson spectroscopy in Wigner-Weyl phase
Thomas Hilger
The coupled quark Dyson-Schwinger and meson Bethe-Salpeter equations in rainbow-ladder truncation for spin-0 mesons are solved in Wigner-Weyl phase in the chiral limit and beyond,…
Towards the spectrum of a GUT from gauge invariance
Pascal Törek, Axel Maas
The description of electroweak physics using perturbation theory is highly successful. Though not obvious, this is due to a subtle field-theoretical effect, the Fröhlich-Morchio-St…
Light-quarkonium spectra and orbital-angular-momentum decomposition in a Bethe-Salpeter-equation approach
T. Hilger, M. Gomez-Rocha, A. Krassnigg
We investigate the light quarkonium spectrum using a covariant Dyson-Schwinger-Bethe-Salpeter-equation approach to QCD. We discuss splittings among as well as orbital angular momen…
Effects of a dressed quark-gluon vertex in pseudoscalar heavy-light mesons
M. Gomez-Rocha, T. Hilger, A. Krassnigg
Using a simple model in the context of the Dyson-Schwinger-Bethe-Salpeter approach, we investigate the effects of a dressed-quark-gluon vertex on pseudoscalar meson masses. In part…
Asymptotic freedom in the front-form Hamiltonian for quantum chromodynamics of gluons
Maria Gomez-Rocha, Stanislaw D. Glazek
Asymptotic freedom of gluons in QCD is obtained in the leading terms of their renormalized Hamiltonian in the Fock space, instead of considering virtual Green's functions or scatte…
Masses of J^PC =1^-+ exotic quarkonia in a Bethe-Salpeter-equation approach
T. Hilger, M. Gomez-Rocha, A. Krassnigg
We investigate the properties of mesons with the exotic J^PC = 1^-+ quantum numbers. Starting out from the light-quark domain, where the π_1 states are used as references, we predi…
On gluon and ghost propagators in linear covariant gauges
Markus Q. Huber
We compute the gluon and ghost propagators of Yang-Mills theory in linear covariant gauges from the coupled system of Dyson-Schwinger equations. For small values of the gauge fixin…
