- 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. l n ⟨ F q ⟩ values for q = 2 –6 are found to increase with increasing values of l n M 2 indicating unambiguously the presence of intermittency in our data sample generated with both chiral and hadronic equations of state (EoS). Although various late processes like meson-meson (MM) and meson-baryon (MB) hadronic re-scattering and/or resonance decays are found to influence the intermittency index significantly, these process could not be held responsible for the observed intermittency in hybrid UrQMD-hydro data. Moreover, the signature of intermittency is also found to exists in different sets of data sample generated with a change in initial conditions such as the start time ( t start ) and transition energy density (TED) of the UrQMD-hydro model confirming the robustness of the observed power law behavior F q ∝ (M 2) α q in our various generated sets of hydro data.
