condensate for light quarks beyond the chiral limit
R. Williams, C. S. Fischer, M. R. Pennington
We determine the condensate for quark masses from zero up to that of the strange quark within a phenomenologically successful modelling of continuum QCD by solving the…
Color-spin locking in a self-consistent Dyson-Schwinger approach
Florian Marhauser, Dominik Nickel, Michael Buballa +1
We investigate the color-spin locked (CSL) phase of spin-one color- superconducting quark matter using a truncated Dyson-Schwinger equation for the quark propagator in Landau gauge…
Goldstone bosons in the color-flavor locked phase
Verena Werth, Michael Buballa, Micaela Oertel
We study pseudoscalar meson excitations in the color-flavor locked phase within a Nambu-Jona-Lasinio-type model by calculating diquark loops.
Renormalization Group Approach towards the QCD Phase Diagram
Bernd-Jochen Schaefer, Jochen Wambach
The idea of the functional renormalization group and one-loop improved renormalization group flows are reviewed. The associated flow equations and nonperturbative approximations sc…
Progress in nonequilibrium quantum field theory III
J. Berges, Sz. Borsanyi
We review recent developments and open questions for the description of nonequilibrium quantum fields, continuing hep-ph/0302210 and hep-ph/0410330.
On the unlocking of color and flavor in color-superconducting quark matter
Dominik Nickel, Reinhard Alkofer, Jochen Wambach
The role of the strange quark mass for the phase structure of QCD at non-vanishing densities is studied by employing a recently developed self-consistent truncation scheme for the…
