33. Joining hard thermal loops with soft deconfinement in the EoS

David Blaschke (University of Wroclaw)

Oral

The hard thermal (dense) loop (HTL) approach for the quark-gluon plasma

and the hadron resonance gas (nuclear statistical equilibrium) model for low-
density hadronic matter are well-studied limits of the equation of state for
strongly interacting matter. However, when investigating the transition
between both phases of QCD in heavy-ion collisions or in Astrophysics, the
question arises how...

13. Geometry and Dynamics in Heavy-ion Collisions Seen by the Femtoscopy in the STAR Experiment

Dr Hanna Zbroszczyk (Warsaw University Of Technology)

Oral

Geometry and dynamics of the particle-emitting source in heavy-ion collisions at high energies can be inferred via femtoscopy method. Two-particle correlations at small relative momentum exploit Quantum Statistics and the Final State Interactions which allow one to study the space-time characteristics of the source of the order of 10−15 m and 10−23 s, respectively. The RHIC Beam Energy Scan...

10. Multiplicity fluctuations in the dynamical clusterization model

Maciej Rybczynski (Jan Kochanowski University (PL))

Oral

We discuss the recently measured event-by-event multiplicity fluctuations in relativistic heavy-ion collisions. It is shown that the observed non-monotonic behaviour of the scaled variance of multiplicity distribution as a function of collision centrality (such effect is not observed in a widely used string-hadronic models of nuclear collisions) can be fully explained by the correlations...

16. Quark Flavor Dependence of the Shear Viscosity in a Quasiparticle Model

Ms Valeriya Mykhaylova (University of Wrocław)

07/04/2019, 12:00

Oral

It is known that the quark-gluon plasma is well described in terms of the perfect fluid dynamics. However, for a more realistic investigation, the dissipative processes quantified by the transport parameters need to be included in the hydrodynamic evolution of the QGP. We study the quark-flavor dependence of the shear viscosity calculated in the relaxation time approximation of the Boltzmann...

15. 4He versus 4Li and production of light nuclei in relativistic heavy-ion collisions

Sylwia Bazak

Oral

We propose to measure the yields of 4He and 4Li in relativistic heavy-ion collisions to
clarify a mechanism of light nuclei production. Since the masses of 4He and 4Li are
almost equal, the yield of 4Li predicted by the thermal model is five times bigger than
that of 4He which reflects the different numbers of internal degrees of freedom of the
two nuclides. Their internal structures are,...
