Charmonium Suppression, Photons, Dileptons and Hadron Ratios in ultrarelativistic Heavy-ion Collisions — •Thorsten Renk1,2, Roland Schneider1,2, Alberto Polleri1, and Wolfram Weise1,2 — 1TU Munich — 2ECT∗, Trento
A careful determination of the conditions probed in ultrarelativistic heavy-ion collisions require the analysis of more than one observable to yield unambiguous results. Using constraints given by an analysis of the freeze-out state based on hadronic observables, we parametrize the space-time behaviour of fireball expansion. Assuming entropy conservation, we use the EoS as obtained in lattice QCD simulations to calculate thermodynamic properties of the fireball. This model is used as the setting in which several processes of interest can now be investigated. Specifically, we calculate dilepton and photon radiation, J/Psi suppression and hadron abundancies at freeze-out within a single framework and find good agreement to data.
