Description

At ultrarelativistic heavy-ion collisions, a new state of matter, the quark-gluon plasma (QGP) is created. For highest collision energies, recent lattice QCD data provide the opportunity to explore Charm quark equilibration in the early QGP phase. We propose a new method to determine the Charm quark equilibration temperature and volume from second and fourth order net-Charm susceptibilities together with experimentally measured multiplicity fluctuations. Furthermore, we present first perturbative results for the second and fourth order Charm quark susceptibilities and their ratio.
