Dyson-Schwinger approach to color superconductivity at finite temperature and density
Daniel Müller, Michael Buballa, Jochen Wambach
We investigate the phases of dense QCD matter at finite temperature with Dyson-Schwinger equations for the quark propagator for N_f=2+1 flavors. For the gluon propagator we take a…
Chiral restoration effects on the shear viscosity of a pion gas
Klaus Heckmann, Michael Buballa, Jochen Wambach
We investigate the shear viscosity of a pion gas in relativistic kinetic theory, using the Nambu-Jona-Lasinio model to construct the pion mass and the pi-pi interaction at finite t…
Isospin Fluctuations in QCD and Relativistic Heavy-Ion Collisions
M. Prakash, R. Rapp, J. Wambach +1
We address the role of fluctuations in strongly interacting matter during the dense stages of a heavy-ion collision through its electromagnetic emission. Fluctuations of isospin ch…
Renormalization Group Flow Equations For The Scalar O(N) Theory
B. -J. Schaefer, O. Bohr, J. Wambach
Self-consistent new renormalization group flow equations for an O(N)-symmetric scalar theory are approximated in next-to-leading order of the derivative expansion. The Wilson-Fishe…
Meson loop effects in the NJL model at zero and non-zero temperature
M. Oertel, M. Buballa, J. Wambach
We compare two different possibilities to include meson-loop corrections in the Nambu-Jona-Lasinio model: a strict 1/N_c-expansion in next-to-leading order and a non-perturbative s…
Meson Properties in the 1/N_c-corrected NJL model
M. Oertel, M. Buballa, J. Wambach
Properties of mesons are investigated within the Nambu--Jona-Lasinio model. We include meson-loop corrections, which are generated via a systematic 1/N_c-expansion in next-to-leadi…
