Abstract We argue that hadron multiplicities in central high energy nucleus–nucleus collisions are established very close to the phase boundary between hadronic and quark matter. In the hadronic picture this can be described by multi-particle collisions whose importance is strongly enhanced due to the high particle density in the phase transition region. As a consequence of the rapid fall-off of the multi-particle scattering rates the experimentally determined chemical freeze-out temperature is… 
Relativistic Nuclear Collisions and the QCD Phase Boundary
In nucleus-nucleus collisions at ultra-relativistic energies matter is formed with initial energy density significantly exceeding the critical energy density for the transition from hadronic to
Chemical freeze-out in heavy ion collisions at large baryon densities
Abstract We argue that the chemical freeze-out in heavy ion collisions at high baryon density is not associated to a phase transition or rapid crossover. We employ the linear nucleon–meson model with
Universal chemical freeze-out as a phase transition signature
It is shown that kinetic freeze-out in relativistic heavy-ion collisions invariably entails a non-trivial dependence of the freeze-out temperature on the collision centrality. The centrality
The QCD Phase Diagram and Hadron Formation in Relativistic Nuclear Collisions
We analyze hadrochemical freeze-out in central collisions of heavy nuclei at AGS, SPS and LHC energies. Employing the UrQMD hybrid transport model we study the effects of the final hadron/resonance
The horn, the hadron mass spectrum and the QCD phase diagram – the statistical model of hadron production in central nucleus-nucleus collisions
We present the status of the description of hadron production in central nucleus-nucleus collisions within the statistical model . The recent inclusion of very high-mass resonances and the sigma
Dense nucleonic matter and the renormalization group
Fluctuations are included in a chiral nucleon-meson model within the framework of the functional renormalization group. The model, with parameters fitted to reproduce the nuclear liquid-gas phase
The QCD phase boundary from quark–gluon dynamics
We study one-flavor QCD at finite temperature and chemical potential using the functional renormalization group. We discuss the chiral phase transition in QCD and its order with its underlying
QCD at nonzero temperature and density
The properties of hot hadronic matter are of great importance to the studies of heavy-ion collisions, cosmology and compact star formation. I briefly outli ne the current methods in use in the
Hadron production in ultra-relativistic nuclear collisions: Quarkyonic matter and a triple point in the phase diagram of QCD
We argue that features of hadron production in relativistic nuclear collisions, mainly at CERN-SPS energies, may be explained by the existence of three forms of matter: Hadronic Matter, Quarkyonic
High energy hadron production as self-organized criticality
In high energy nuclear collisions, production rates of light nuclei as well as those of hadrons and hadronic resonances agree with the predictions of an ideal gas at a temperature [Formula: see

Universal pion freeze-out in heavy-ion collisions.
TLDR
It is shown that freeze- out occurs when the mean free path of pions lambda(f) reaches a value of about 1 fm, which is much smaller than the spatial extent of the system at freeze-out.
