20. Partial correlation analysis in ultra-relativistic nuclear collisions

Adam Olszewski (UJK Kielce)

We argue that statistical data analysis of two-particle correlations in ultra-relativistic heavy-ion collisions may be efficiently carried out with the technique of partial covariance. We show that in the superposition approach the presented framework allows onę to impose constraints on the number of sources rather than hadrons, which leads to better understanding of the initial-state physics....

4. From electromagnetic effects to fire-streaks in heavy ion collisions

Miroslaw Marek Kielbowicz (Polish Academy of Sciences (PL))

Our presentation will be based on our recent paper [1].

We construct a new, simple model of the heavy ion collision, local in the impact parameter plane. This model can be regarded as a new realization of the ``fire-streak'' approach, originally applied to studies of lower energy nucleus-nucleus reactions.

Starting from local energy and momentum conservation, we provide a full description of...

7. Angular correlations of identified hadrons in the STAR BES data

Andrzej Lipiec (Warsaw University of Technology)

The angular correlation function (CF) indicates the correlation of particles in the relative pseudo-rapidity and relative azimuthal angle. It is used to study the properties of strongly interacting matter at relativistic energies. Recent results from the ALICE experiment at the LHC show unexpected structures of CF in the proton-proton and antiproton-antiproton correlations. Also results from...

12. Net-baryon number fluctuations in the quark-meson-nucleon model at finite baryon density

Michał Marczenko (University of Wrocław)

One of the most significant aspects of QCD thermodynamics is understanding how the transition from hadrons to their constituents—quarks and gluons—relates to the underlying deconfinement and chiral dynamics. This is of major relevance for heavy-ion collisions, as well as in the study of cold and dense systems, such as compact stars. The latter, however, is often studied exclusively in models...
