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,…
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…
Jets and Underlying Events at LHC Energies
A. G. Agócs, G. G. Barnaföldi, P. Lévai
Jet-matter interaction remains a central question and a theoretical challenge in heavy-ion physics and might become important in high-multiplicity events in proton-proton collision…
On the evolution of an entangled lepton-neutrino pair
Balazs Meszena, Andras Patkos
The evolution of the entangled muon-neutrino system emerging from charged pion decay is explored both in vacuum and in matter. The study is based on a Weisskopf-Wigner type wave-pa…
Strange mass dependence of the tricritical point in the U(3)_L x U(3)_R chiral sigma model
A. Jakovac, Zs. Szep
We study the strange quark mass dependence of the tricritical point of the U(3)_L x U(3)_R linear sigma model in the chiral limit. Assuming that the tricritical point is at a large…
Influence of the Polyakov loop on the chiral phase transition in the two flavor chiral quark model
G. Marko, Zs. Szep
The SU(2)_L x SU(2)_R chiral quark model consisting of the (sigma,pi) meson multiplet and the constituent quarks propagating on the homogeneous background of a temporal gauge field…
