van der Waals Interactions and Hadron Resonance Gas: Role of resonance widths modeling on conserved charges fluctuations
Volodymyr Vovchenko, Paolo Alba, Mark I. Gorenstein +1
The quantum van der Waals (QvdW) extension of the ideal hadron resonance gas (HRG) model which includes the attractive and repulsive interactions between baryons -- the QvdW-HRG mo…
Critical point of nuclear matter and beam energy dependence of net proton number fluctuations
Volodymyr Vovchenko, Lijia Jiang, Mark I. Gorenstein +1
The beam energy dependence of net baryon number susceptibilities is studied in the framework of the hadron resonance gas model with the attractive and repulsive van der Waals inter…
Cluster Expansion Model for QCD Baryon Number Fluctuations: No Phase Transition at
Volodymyr Vovchenko, Jan Steinheimer, Owe Philipsen +1
A Cluster Expansion Model (CEM), representing a relativistic extension of Mayer's cluster expansion, is constructed to study baryon number fluctuations in QCD. The temperature depe…
Beth-Uhlenbeck approach for repulsive interactions between baryons in a hadron gas
Volodymyr Vovchenko, Anton Motornenko, Mark I. Gorenstein +1
The quantum mechanical Beth-Uhlenbeck (BU) approach for repulsive hard-core interactions between baryons is applied to the thermodynamics of a hadron gas. The second virial coeffic…
Modeling baryonic interactions with the Clausius-type equation of state
Volodymyr Vovchenko, Mark I. Gorenstein, Horst Stoecker
The quantum statistical Clausius-based equation of state is used to describe the system of interacting nucleons. The interaction parameters , , and of the model are fixed…
Quantum van der Waals and Walecka models of nuclear matter
R. V. Poberezhnyuk, V. Vovchenko, D. V. Anchishkin +1
A comparable study of the quantum van der Waals and Walecka models of nuclear matter is presented. Each model contains two parameters which characterize the repulsive and attractiv…
Repulsive baryonic interactions and lattice QCD observables at imaginary chemical potential
Volodymyr Vovchenko, Attila Pasztor, Zoltan Fodor +2
The first principle lattice QCD methods allow to calculate the thermodynamic observables at finite temperature and imaginary chemical potential. These can be compared to the predic…
Multicomponent van der Waals equation of state: Applications in nuclear and hadronic physics
Volodymyr Vovchenko, Anton Motornenko, Paolo Alba +3
A generalization of the quantum van der Waals equation of state for a multi-component system in the grand canonical ensemble is proposed. The model includes quantum statistical eff…
Bose-Einstein condensation and liquid-gas phase transition in alpha-matter
L. M. Satarov, M. I. Gorenstein, A. Motornenko +3
Systems of Bose particles with both repulsive and attractive interactions are studied using the Skyrme-like mean-field model. The phase diagram of such systems exhibits two special…
Workshop on Excited Hyperons in QCD Thermodynamics at Freeze-Out (YSTAR2016) Mini-Proceedings
P. Alba, M. Amaryan, V. Begun +38
This Workshop brought top experts, researchers, postdocs, and students from high-energy heavy ion interactions, lattice QCD and hadronic physics communities together. YSTAR2016 dis…
Missing resonance decays in thermal models
V. V. Begun, V. Yu. Vovchenko, M. I. Gorenstein
Detailed information on decay channel probabilities is absent for many high mass resonances, which are typically included in thermal models. In these cases, the sum over all known…
Equations of state for real gases on the nuclear scale
Volodymyr Vovchenko
The formalism to augment the classical models of equation of state for real gases with the quantum statistical effects is presented. It allows an arbitrary excluded volume procedur…
