A nonlinear classical model for the decay widths of Isoscalar Giant Monopole Resonances
P. K. Papachristou, E. Mavrommatis, V. Constantoudis +2
The decay of the Isoscalar Giant Monopole Resonance (ISGMR) in nuclei is studied by means of a nonlinear classical model consisting of several noninteracting nucleons (particles) m…
Hyperon-nucleon single-particle potentials with low-momentum interactions
Haris Djapo, Bernd-Jochen Schaefer, Jochen Wambach
Single-particle potentials in Hartree-Fock approximation for different hyperon-nucleon (YN) channels are calculated in the framework of the effective low-momentum YN interaction V_…
Neutrality of the color-flavor-locked phase in a Dyson-Schwinger approach
Dominik Nickel, Reinhard Alkofer, Jochen Wambach
The role of neutrality constraints for the phase structure of QCD at non-vanishing chemical potentials is studied within a self-consistent truncation scheme for the Dyson-Schwinger…
Studying pion effects in the quark propagator
Dominik Nickel, Christian S. Fischer, Jochen Wambach
Within the framework of Schwinger-Dyson and Bethe-Salpeter equations we investigate the importance of pions for the quark-gluon interaction. To this end we choose a truncation for…
Hadronic unquenching effects in the quark propagator
Christian S. Fischer, Dominik Nickel, Jochen Wambach
We investigate hadronic unquenching effects in light quarks and mesons. Within the non-perturbative continuum framework of Schwinger-Dyson and Bethe-Salpeter equations we quantify…
The Phase Structure of the Polyakov--Quark-Meson Model
Bernd-Jochen Schaefer, Jan M. Pawlowski, Jochen Wambach
The relation between the deconfinement and chiral phase transition is explored in the framework of an Polyakov-loop-extended two-flavor quark-meson (PQM) model. In this model the P…
