Nuclear Transparency Effect in the Strongly Interacting Matter

TL;DR

This paper explores how nuclear transparency measurements in high-energy nuclear collisions can reveal new phases of strongly interacting matter and identify the QCD critical point, emphasizing the need for enriched experimental data.

Contribution

It proposes using nuclear transparency effects to detect new phases and the QCD critical point, highlighting the importance of upcoming experimental data from NICA/MPD and CBM setups.

Findings

Potential confirmation of the 'horn' effect in nuclear collisions

Identification of new phases of strongly interacting matter

Insights into the QCD critical point

Abstract

We discuss that the results of study of the nuclear transparency effect in nuclear-nuclear collisions at relativistic and ultrarelativistic energies could help to extract the information on new phases of the strongly interacting matter as well as the QCD critical point. The results could provide further confirmation of the existence of the "horn" effect which had initially been obtained for the ratio of average values of K+ to pi+ -mesons' multiplicity as a function of the initial energies in the NA49 SPS CERN experiment. To observe the "horn" as a function of centrality, the new more enriched experimental data are required. The data which are expected from NICA/MPD JINR and CBM GSI setups could fulfill the requirement.
