On the analytic structure of scalar glueball operators at Born level
Andreas Windisch, Markus Q. Huber, Reinhard Alkofer
We study the analytic structure of the two-point function of the operator F2 which is expected to describe a scalar glueball. The calculation of the involved integrals is complicat…
Self-bound quark matter in the NJL model revisited: from schematic droplets to domain-wall solitons
Michael Buballa, Stefano Carignano
The existence and the properties of self-bound quark matter in the NJL model at zero temperature are investigated in mean-field approximation, focusing on inhomogeneous structures…
Thermodynamic instabilities in dynamical quark models with complex conjugate mass poles
Sanjin Benić, David Blaschke, Michael Buballa
We show that the CJT thermodynamic potential of dynamical quark models with a quark propagator represented by complex conjugate mass poles inevitably exhibits thermodynamic instabi…
Fluctuations in the quark-meson model for QCD with isospin chemical potential
Kazuhiko Kamikado, Nils Strodthoff, Lorenz von Smekal +1
We study the two-flavor quark-meson (QM) model with the functional renormalization group (FRG) to describe the effects of collective mesonic fluctuations on the phase diagram of QC…
Universal Aspects of QCD-like Theories
Lorenz von Smekal
In these lectures I review some basic examples of how the concepts of universality and scaling can be used to study aspects of the chiral and the deconfinement transition, if not i…
