The - and -nucleus interactions and the search for , - mesic states
Steven D. Bass, Volker Metag, Pawel Moskal
The isoscalar and mesons are special in QCD, being linked both to chiral symmetry and to non-perturbative glue associated with the axial anomaly. The properties of these m…
Quenched glueball spectrum from functional equations
Markus Q. Huber, Christian S. Fischer, Hèlios Sanchis-Alepuz
We give an overview of results for the quenched glueball spectrum from two-body bound state equations based on the 3PI effective action. The setup, which uses self-consistently cal…
Higher spin glueballs from functional methods
Markus Q. Huber, Christian S. Fischer, Helios Sanchis-Alepuz
We calculate the glueball spectrum for spin up to J=4 and positive charge parity in pure Yang-Mills theory. We construct the full bases for J=0,1,2,3,4 and discuss the relation to…
Analytical structure of the equation of state at finite density: Resummation versus expansion in a low energy model
Swagato Mukherjee, Fabian Rennecke, Vladimir V. Skokov
For theories plagued with a sign problem at finite density, a Taylor expansion in the chemical potential is frequently used for lattice gauge theory based computations of the equat…
On commutator relations in -spherical RGD-systems
Sebastian Bischof
In this paper we investigate the commutator relations for prenilpotent roots which are nested. These commutator relations are trivial in a lot of cases.
Critical endpoint of QCD in a finite volume
Julian Bernhardt, Christian S. Fischer, Philipp Isserstedt +1
We investigate the impact of finite volume and the corresponding restrictions on long-range correlations on the location of the critical endpoint in the QCD phase diagram. To this…
