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…
