Equation of state of QCD matter within the Hagedorn bag-like model
Volodymyr Vovchenko, Mark I. Gorenstein, Carsten Greiner +1
The QCD equation of state at finite temperature and densities of conserved charges is considered in the framework of a Hagedorn bag-like model, incorporating both the finite sizes…
Binomial acceptance corrections for particle number distributions in high-energy reactions
Oleh Savchuk, Roman V. Poberezhnyuk, Volodymyr Vovchenko +1
The binomial acceptance correction procedure is studied for particle number distributions detected in high energy reactions in finite regions of the momentum space. We present acce…
Traces of the nuclear liquid-gas phase transition in the analytic properties of hot QCD
Oleh Savchuk, Volodymyr Vovchenko, Roman V. Poberezhnyuk +2
The nuclear liquid-gas transition at normal nuclear densities, fm, and small temperatures, MeV, has a large influence on analytic properties…
Critical point signatures in the cluster expansion in fugacities
Volodymyr Vovchenko, Carsten Greiner, Volker Koch +1
The QCD baryon number density can formally be expanded into a Laurent series in fugacity, which is a relativistic generalization of Mayer's cluster expansion. We determine properti…
Kinetic freeze-out temperature from yields of short-lived resonances
Anton Motornenko, Volodymyr Vovchenko, Carsten Greiner +1
A method to determine the kinetic freeze-out temperature in heavy-ion collisions from measured yields of short-lived resonances is presented. The resonance production is treated in…
Review of opportunities at the HESR-Collider with PANDA at FAIR
Leonid Frankfurt, Mark Strikman, Alexei Larionov +6
Exciting new scientific opportunities are presented for the PANDA detector at the High Energy Storage Ring in the redefined collider mode, HESR-C,…
Matter And Gravitation In Collisions of heavy ions and neutron stars: equation of state
Anton Motornenko, Jan Steinheimer, Volodymyr Vovchenko +2
The gravitational waves emitted from a binary neutron star merger, as predicted from general relativistic magneto-hydrodynamics calculations, are sensitive to the appearance of qua…
Canonical statistical model analysis of p-p, p-Pb, and Pb-Pb collisions at the LHC
Volodymyr Vovchenko, Benjamin Dönigus, Horst Stoecker
The system-size dependence of hadrochemistry at vanishing baryon density is considered within the canonical statistical model (CSM) with local exact conservation of three conserved…
Chemical freeze-out conditions and fluctuations of conserved charges in heavy-ion collisions within quantum van der Waals model
R. Poberezhnyuk, V. Vovchenko, A. Motornenko +2
The chemical freeze-out parameters in central nucleus-nucleus collisions are extracted consistently from hadron yield data within the quantum van der Waals (QvdW) hadron resonance…

Volodymyr Vovchenko, Jan Steinheimer, Owe Philipsen +1
We explore the QCD equation of state at finite baryon density through an expansion in baryon number fugacity, making use of the recent lattice data on the four leading Fourier coef…
Equation of state for hot QCD and compact stars from a mean field approach
Anton Motornenko, Jan Steinheimer, Volodymyr Vovchenko +2
The thermodynamic properties of high temperature and high density QCD-matter are explored within the Chiral SU(3)-flavor parity-doublet Polyakov-loop quark-hadron mean-field model,…
