Study of the behavior of nuclear modification factor in freeze-out state

TL;DR

This paper investigates how the nuclear modification factor behaves at freeze-out in high-energy Au-Au collisions, aiming to identify signals of quark-gluon plasma formation through nuclear transparency effects.

Contribution

It explores the relationship between nuclear transparency and the emergence of quark-gluon plasma using the FASTMC simulation at RHIC energies.

Findings

Critical changes in transparency may indicate new phases of strongly interacting matter.

Nuclear transparency effects could serve as signals for QGP formation.

Simulation results support the connection between transparency and phase transitions.

Abstract

One of the latest trends in the advancement of experimental high-energy physics is to identify the quark gluon plasma (QGP) predicted qualitatively by quantum chromodynamics (QCD). We discuss whether nuclear transparency effect which is considered an important phenomenon, connected with dynamics of hadron-nuclear and nuclear-nuclear interactions could reflect some particular properties of the medium. FASTMC is used for Au-Au collision at RHIC energies. Critical change in the transparency is considered a signal on the appearance of new phases of strongly interacting matter and the QGP.
