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…
Possible origin of HADES data on proton number fluctuations in Au+Au collisions
O. Savchuk, R. V. Poberezhnyuk, M. I. Gorenstein
Recent data of the HADES Collaboration in Au+Au central collisions at GeV indicate large proton number fluctuations inside one unit of rapidity around midra…
Phase diagram of interacting pion matter and isospin charge fluctuations
O. S. Stashko, O. V. Savchuk, R. V. Poberezhnyuk +2
Equation of state and electric (isospin) charge fluctuations are studied for matter composed of interacting pions. The pion matter is described by self interacting scalar fields vi…
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…
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…
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…
