Why are the dilepton temperatures at the relativistic heavy-ion colliders are constant, T ~ 0.3 GeV?
Horst Stoecker, Leonid M. Satarov, Volodymyr Vovchenko
The STAR collaboration at RHIC and the ALICE collaboration at the LHC have reported dielectron spectra in the intermediate mass region, M = (1-3) GeV, which reveal a strikingly con…
Locating the QCD critical point through contours of constant entropy density
Hitansh Shah, Mauricio Hippert, Jorge Noronha +2
We propose a new method to investigate the existence and location of the conjectured high-temperature critical point of strongly interacting matter via contours of constant entropy…
Systematics of the chemical freeze-out line in the high baryon density regime explored at SIS100
Emma Lilith Hofmann, Tom Reichert, Volodymyr Vovchenko +2
The systematic uncertainties of chemical freeze-out fits at SIS100 energies (Au+Au reactions at GeV) are studied using UrQMD simulations. Although hadron produc…
Exploring the properties of the Hadronic Phase in Heavy-Ion Collisions at RHIC Energies via Partial Chemical Equilibrium
Rishabh Sharma, Chitrasen Jena, Volodymyr Vovchenko
The hadronic phase in heavy-ion collisions plays a crucial role in shaping the final-state hadron abundances. In this work, we study Au+Au collisions at = 7.7-2…
High-order cumulants and correlation functions near the critical point from molecular dynamics
Volodymyr A. Kuznietsov, Roman Poberezhniuk, Mark I. Gorenstein +2
We present a systematic investigation of particle number fluctuations in the crossover region near the critical endpoint of a first-order phase transition using molecular dynamics…
Acceptance dependence of factorial cumulants, long-range correlations, and the antiproton puzzle
Adam Bzdak, Volker Koch, Volodymyr Vovchenko
We analyze joint factorial cumulants of protons and antiprotons in relativistic heavy-ion collisions and point out that they obey the scaling $\hat{C}_{nm}^{p,\bar{p}} \propto \lan…
