Signature of intermittency in hybrid UrQMD-hydro data at 10 AGeV Au+Au collisions

TL;DR

This study uses scaled factorial moments to analyze hybrid UrQMD-hydro simulated Au+Au collisions at 10 AGeV, revealing evidence of intermittency influenced by hydrodynamic evolution, independent of late-stage hadronic processes.

Contribution

It demonstrates the presence of intermittency in hybrid UrQMD-hydro data and assesses the impact of hydrodynamic evolution on this phenomenon, distinguishing it from late-stage hadronic effects.

Findings

Intermittency observed in the data sample.

Hydrodynamic evolution influences intermittency.

Late hadronic processes do not account for observed intermittency.

Abstract

An attempt has been made, in the light of scaled factorial moment (SFM) analysis, to investigate hybrid UrQMD hydro generated events of Au+Au collisions at 10 AGev to realize the role of hydrodynamic evolution on observed intermittency, if any. ln <F_q> values for q = 2 - 6 are found to increase with increasing values of ln M^2 indicating unambiguously the presence of intermittency in our data sample generated with both chiral and hadronic equation of states (EOS). Although various late processes like meson-meson (MM) and meson-baryon (MB) hadronic rescattering and/or resonance decays are to influence the intermittency index significantly, these processes could not be held responsible for the observed intermittency in hybrid UrQMD hydro data.
