Dileptons and Photons from Coarse-Grained Microscopic Dynamics and Hydrodynamics Compared to Experimental Data
Joseph Kapusta
We compute the radiation of dileptons and photons using relativistic hydrodynamics and a coarse-grained version of the microscopic event generator UrQMD, both of which provide a go…
Dileptons and Photons from Coarse-Grained Microscopic Dynamics and Hydrodynamics Compared to Experimental Data
P. Huovinen, M. Belkacem, P. J. Ellis +1
Radiation of dileptons and photons from high energy nuclear collisions provides information on the space-time evolution of the hot dense matter produced therein. We compute this ra…
Properties of and Mesons at Finite Temperature and Density as Inferred from Experiment
V. L. Eletsky, M. Belkacem, P. J. Ellis +1
The mass shift, width broadening, and spectral density for the and mesons in a heat bath of nucleons and pions are calculated using a general formula which relates the self…
Enhanced Strange Particle Yields - Signal of a Phase of Massless Particles ?
Sven Soff, D. Zschiesche, M. Bleicher +8
The yields of strange particles are calculated with the UrQMD model for p,Pb(158 AGeV)Pb collisions and compared to experimental data. The yields are enhanced in central collisions…
Equilibrium and non-equilibrium effects in relativistic heavy ion collisions
L. V. Bravina, E. E. Zabrodin, M. I. Gorenstein +10
The hypothesis of local equilibrium (LE) in relativistic heavy ion collisions at energies from AGS to RHIC is checked in the microscopic transport model. We find that kinetic, ther…
Symmetry conserving non-perturbative s-wave renormalization of the pion in hot and baryon dense medium
Z. Aouissat, M. Belkacem
A non-perturbative s-wave renormalization of the pion in a hot and baryon rich medium is presented. This approach proceeds via a mapping of the canonical pion into the axial Noethe…
