A dynamical quasiparticle approach for the Quark-Gluon-Plasma bulk and transport properties
Hamza Berrehrah, Elena Bratkovskaya, Thorsten Steinert +1
The properties of quantum-chromo dynamics (QCD) nowadays are accessable by lattice QCD calculations at vanishing quark chemical potential =0 but often lack a transparent physi…
Degrees of Freedom of the Quark Gluon Plasma, tested by Heavy Mesons
H. Berrehrah, M. Nahrgang, T. Song +5
Heavy quarks (charm and bottoms) are one of the few probes which are sensitive to the degrees of freedom of a Quark Gluon Plasma (QGP), which cannot be revealed by lattice gauge ca…
The quark susceptibility in a generalized dynamical quasiparticle model
Hamza Berrehrah, Wolfgang Cassing, Elena Bratkovskaya +1
The quark susceptibility at zero and finite quark chemical potential provides a critical benchmark to determine the quark-gluon-plasma (QGP) degrees of freedom in relation to…
Heavy quark scattering and quenching in a QCD medium at finite temperature and chemical potential
H. Berrehrah, E. Bratkovskaya, W. Cassing +2
The heavy quark collisional scattering on partons of the quark gluon plasma (QGP) is studied in a QCD medium at finite temperature and chemical potential. We evaluate the effects o…
Transport coefficients of heavy quarks around at finite quark chemical potential
H. Berrehrah, P. B. Gossiaux, J. Aichelin +3
The interactions of heavy quarks with the partonic environment at finite temperature and finite quark chemical potential are investigated in terms of transport coefficien…
Dynamical collisional energy loss and transport properties of on- and off-shell heavy quarks in vacuum and in the Quark Gluon Plasma
Hamza Berrehrah, Pol-Bernard Gossiaux, Jörg Aichelin +2
In this study we evaluate the dynamical collisional energy loss of heavy quarks, their interaction rate as well as the different transport coefficients (drag and diffusion coeffici…
Transport coefficients from the Nambu-Jona-Lasinio model for
Rudy Marty, Elena Bratkovskaya, Wolfgang Cassing +2
We calculate the shear and bulk viscosities as well as the electric conductivity and heat conductivity within the Nambu-Jona-Lasinio model for 3 flavo…
Towards the dynamical study of heavy-flavor quarks in the Quark-Gluon-Plasma
H. Berrehrah, E. Bratkovskaya, W. Cassing +2
Within the aim of a dynamical study of on- and off-shell heavy quarks Q in the quark gluon plasma (QGP) - as produced in relativistic nucleus-nucleus collisions - we study the heav…
