Description
The study of QGP formation in RHIC experiments provides insight into the
strong force that binds quarks and gluons, also enriching our knowledge about the conditions of the early universe. Several measurements from both small and large collision systems, examining the same observables such as strangeness enhancement across different energies, suggest QGP-like behavior in all these systems. Recently, STAR experiment at RHIC collected a large data sample in oxygen-oxygen (O + O) collisions at √ sNN = 200 GeV. Oxygen is the lightest nucleus compared to the Au, Cu and P b and expected to overlap the multiplicity coverage between small and large systems at RHIC. In this study, we have used recently developed version of the EPOS (EPOS4) to study the production of identified particles (π±, K± and p(p)) in O + O collisions at √sNN = 200 GeV. Predictions of transverse momentum (pT) spectra, ⟨pT⟩,integrated yield (dN/dy) for different centrality classes are studied. To provide insight into the collective nature of the produced particles, we look into the pT-differential particle ratios K/π and p/π. It is observed that the EPOS4 successfully produce the typical shape of the charge particle multiplicity (dN/dη) and mean transverse momentum (⟨pT⟩). Additionally, EPOS4 in O + O collisons at √sNN = 200 GeV also predict the final multiplicity overlap among pp, Cu − Cu, dAu and Au − Au collisions.
