Centrality dependence of proton and light nuclei yields as a consequence of baryon annihilation in the hadronic phase
Volodymyr Vovchenko, Volker Koch
The centrality dependence of the ratio measured by the ALICE Collaboration in 5.02 TeV Pb-Pb collisions indicates a statistically significant suppression with the increase of…
Constraints on hadron resonance gas interactions via first-principles Lattice QCD susceptibilities
Jamie M. Karthein, Volker Koch, Claudia Ratti +1
We investigate extensions of the Hadron Resonance Gas (HRG) Model beyond the ideal case by incorporating both attractive and repulsive interactions into the model. When considering…
Long Range Plan: Dense matter theory for heavy-ion collisions and neutron stars
Alessandro Lovato, Travis Dore, Robert D. Pisarski +61
Since the release of the 2015 Long Range Plan in Nuclear Physics, major events have occurred that reshaped our understanding of quantum chromodynamics (QCD) and nuclear matter at l…
Quarkyonic or baryquark matter? On the dynamical generation of momentum space shell structure
Volker Koch, Volodymyr Vovchenko
We study the equation of state of a mixture of (quasi-)free constituent quarks and nucleons with hard-core repulsion at zero temperature. Two opposite scenarios for the realization…
Phase transition amplification of proton number fluctuations in nuclear collisions from a transport model approach
O. Savchuk, R. V. Poberezhnyuk, A. Motornenko +3
The time evolution of particle number fluctuations in nuclear collisions at intermediate energies ( GeV) is studied by means of the UrQMD-3.5 transport mode…
Fluctuations in heavy ion collisions and global conservation effects
Roman V. Poberezhnyuk, Volodymyr Vovchenko, Oleh Savchuk +3
Subensemble is a type of statistical ensemble which is the generalization of grand canonical and canonical ensembles. The subensemble acceptance method (SAM) provides general formu…
Energy dependence of light hypernuclei production in heavy-ion collisions from a coalescence and statistical-thermal model perspective
Tom Reichert, Jan Steinheimer, Volodymyr Vovchenko +2
A comparison of light hypernuclei production, from UrQMD+coalescence and the thermal model, in heavy ion collisions over a wide range of beam energies and system sizes is presented…
Fluctuations of conserved charges in hydrodynamics and molecular dynamics
Volodymyr Vovchenko
I present an overview of recent theoretical results on fluctuations of conserved charges in heavy-ion collisions obtained in relativistic hydrodynamics and molecular dynamics frame…
Enhanced dilepton emission from a phase transition in dense matter
O. Savchuk, A. Motornenko, J. Steinheimer +4
It is demonstrated that the presence of a phase transition in heavy ion collisions, at beam energies that probe dense QCD matter, leads to a significant enhancement of the dilepton…
QCD Phase Structure and Interactions at High Baryon Density: Continuation of BES Physics Program with CBM at FAIR
D. Almaalol, M. Hippert, J. Noronha-Hostler +41
We advocate for an active US participation in the international collaboration of the CBM experiment that will allow the US nuclear physics program to build on its successful explor…
Proton number cumulants and correlation functions from hydrodynamics and the QCD phase diagram
Volodymyr Vovchenko, Volker Koch, Chun Shen
We analyze the behavior of (net-)proton number cumulants in central collisions of heavy ions across a broad collision energy range by utilizing hydrodynamic simulations. The calcul…
Cooper-Frye sampling with short-range repulsion
Volodymyr Vovchenko
This work incorporates the effect of short-range repulsion between particles into the Cooper-Frye hadron sampling procedure. This is achieved by means of a rejection sampling step,…
Thermodynamic approach to proton number fluctuations in baryon-rich heavy-ion matter created at moderate collision energies
Volodymyr Vovchenko, Volker Koch
We develop a framework to relate proton number cumulants measured in heavy-ion collisions within a momentum space acceptance to the susceptibilities of baryon number, assuming that…
Thermal-model-based characterization of heavy-ion-collision systems at chemical freeze-out
Jamie M. Karthein, Paolo Alba, Valentina Mantovani-Sarti +6
We investigate the chemical freeze-out in heavy-ion collisions (HICs) and the impact of the hadronic spectrum on thermal model analyses. Detailed knowledge of the hadronic spectrum…
Critical point particle number fluctuations from molecular dynamics
Volodymyr A. Kuznietsov, Oleh Savchuk, Mark I. Gorenstein +2
We study fluctuations of particle number in the presence of critical point by utilizing molecular dynamics simulations of the classical Lennard-Jones fluid in a periodic box. The n…
