Particlization of an interacting hadron resonance gas with global conservation laws for event-by-event fluctuations in heavy-ion collisions
Volodymyr Vovchenko, Volker Koch
We revisit the problem of particlization of a QCD fluid into hadrons and resonances at the end of the fluid dynamical stage in relativistic heavy-ion collisions in a context of flu…
Higher order conserved charge fluctuations inside the mixed phase
Roman V. Poberezhnyuk, Oleh Savchuk, Mark I. Gorenstein +2
General formulas are presented for higher order cumulants of the conserved charge statistical fluctuations inside the mixed phase. As a particular example the van der Waals model i…
Pion condensation in the early Universe at nonvanishing lepton flavor asymmetry and its gravitational wave signatures
Volodymyr Vovchenko, Bastian B. Brandt, Francesca Cuteri +3
We investigate the possible formation of a Bose-Einstein condensed phase of pions in the early Universe at nonvanishing values of lepton flavor asymmetries. A hadron resonance gas…
Cumulants of multiple conserved charges and global conservation laws
Volodymyr Vovchenko, Roman V. Poberezhnyuk, Volker Koch
We analyze the behavior of cumulants of conserved charges in a subvolume of a thermal system with exact global conservation laws by extending a recently developed subensemble accep…
Bose-Einstein condensation phenomenology in systems with repulsive interactions
Oleh Savchuk, Yehor Bondar, Oleksandr Stashko +4
The role of repulsive interactions in statistical systems of Bose particles is investigated. Three different phenomenological frameworks are considered: a mean field model, an excl…
Hadron resonance gas with van der Waals interactions
Volodymyr Vovchenko
An overview of a hadron resonance gas (HRG) model that includes van der Waals interactions between hadrons is presented. Applications of the excluded volume HRG model to heavy-ion…
Critical point fluctuations: Finite size and global charge conservation effects
Roman V. Poberezhnyuk, Oleh Savchuk, Mark I. Gorenstein +6
We investigate simultaneous effects of finite system size and global charge conservation on thermal fluctuations in the vicinity of a critical point. For that we consider a finite…
Feeddown contributions from unstable nuclei in relativistic heavy-ion collisions
Volodymyr Vovchenko, Benjamin Dönigus, Behruz Kardan +2
We estimate the feeddown contributions from decays of unstable and nuclei to the final yields of protons, deuterons, tritons, He, and He produced in relativ…
Connecting fluctuation measurements in heavy-ion collisions with the grand-canonical susceptibilities
Volodymyr Vovchenko, Oleh Savchuk, Roman V. Poberezhnyuk +2
We derive the relation between cumulants of a conserved charge measured in a subvolume of a thermal system and the corresponding grand-canonical susceptibilities, taking into accou…
QCD equation of state at vanishing and high baryon density: Chiral Mean Field model
Anton Motornenko, Jan Steinheimer, Volodymyr Vovchenko +2
The thermodynamic properties of high temperature and high density QCD-matter are studied using the Chiral SU(3)-flavor parity-doublet Polyakov-loop quark-hadron mean-field model, C…
