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. values for –6 are found to increase with increasing values of 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 () and transition energy density (TED) of the UrQMD-hydro model confirming the robustness of the observed power law behavior in our various generated sets of hydro data.
