The effect of the Polyakov loop on the chiral phase transition
G. Marko, Zs. Szep
The Polyakov loop is included in the SU(2)_L x SU(2)_R chiral quark-meson model by considering the propagation of the constituent quarks, coupled to the (sigma,pi) meson multiplet,…
Imbalances in directed multigraphs
S. Pirzada, T. A. Naikoo, U. Samee +1
In a directed multigraph, the imbalance of a vertex is defined as , where and denote the outdegree an…
Recent results on QCD thermodynamics: lattice QCD versus Hadron Resonance Gas model
Szabolcs Borsanyi, Zoltan Fodor, Christian Hoelbling +4
We present our most recent investigations on the QCD cross-over transition temperatures with 2+1 staggered flavours and one-link stout improvement [JHEP 1009:073, 2010]. We extend…
Spectra, elliptic flow and azimuthally sensitive HBT radii from Buda-Lund model for sqrt(s(NN)) = 200 GeV Au+Au collisions
A. Ster, M. Csanad, T. Csorgo +2
We present calculations of elliptic flow and azimuthal dependence of correlation radii in the ellipsoidally symmetric generalization of the Buda-Lund hydrodynamic model of hadron p…
Completely positive mappings and mean matrices
Adam Besenyei, Denes Petz
Some real functions f induce mean of positive numbers and the matrix monotonicity gives a possibility for means of positive definite matrices. Moreover, such a function f can defin…
Note on triangle anomaly with improved momentum cutoff
G. Cynolter, E. Lendvai
A Lorentz and gauge symmetry preserving regularization method has been proposed recently in 4 dimension based on Euclidean momentum cutoff. It is shown that the triangle anomaly ca…
