Finite-density gauge correlation functions in QC2D
Tamer Boz, Ouraman Hajizadeh, Axel Maas +1
2-color QCD is the simplest QCD-like theory which is accessible to lattice simulations at finite density. It therefore plays an important role to test qualitative features and to p…
Bound state properties from the Functional Renormalisation Group
Reinhard Alkofer, Axel Maas, Walid Ahmed Mian +4
We discuss an approach for accessing bound state properties, like mass and decay width, of a theory within the functional renormalisation group approach. An important cornerstone i…
Exploratory study of the off-shell properties of the weak vector bosons
Axel Maas, Sebastian Raubitzek, Pascal Törek
Gauge invariance requires even in the weak interactions that physical, observable particles are described by gauge-invariant composite operators. Such operators have the same struc…
The quenched SU(2) adjoint scalar propagator in minimal Landau gauge
Axel Maas
It is a long-standing question whether the confinement of matter fields in QCD has an imprint in the (gauge-dependent) correlation functions, especially the propagators. In particu…
On observable particles in theories with a Brout-Englert-Higgs effect
Pascal Törek, Axel Maas
Even at weak coupling the physical, observable spectrum of gauge theories with a Brout-Englert-Higgs effect can deviate from the elementary one of perturbation theory. This can be…
The spectrum of an SU(3) gauge theory with a fundamental Higgs field
Axel Maas, Pascal Törek
In gauge theories, the physical, experimentally observable spectrum consists only of gauge-invariant states. This spectrum can be different from the elementary spectrum even at wea…
