Hadron production and QGP Hadronization in Pb-Pb collisions at LHC    [PDF]

Michal Petran, Jean Letessier, Vojtech Petracek, Johann Rafelski

We show that all central rapidity hadron yields measured in heavy ion collisions at LHC are well described by the chemical non-equilibrium statistical hadronization model (SHM), where the chemically equilibrated QGP source breaks up directly into hadrons. SHM parameters are obtained as a function of geometric centrality of colliding ions, and we compare LHC with RHIC62 results. We predict yields of unobserved hadrons and address anti-matter production. The physical properties of the quark-gluon plasma fireball particle source show universality of hadronization conditions at LHC and RHIC.
