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…
Single electrons from heavy-flavor mesons in relativistic heavy-ion collisions
Taesoo Song, Hamza Berrehrah, Juan M. Torres-Rincon +4
We study the single electron spectra from and meson semileptonic decays in Au+Au collisions at 200, 62.4, and 19.2 GeV by employing the parton-hadron-s…
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…
