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. \(ln\langle F_{q}\rangle \) values for \(q=2\)–6 are found to increase with increasing values of \(lnM^{2}\) 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 \(F_{q} \propto (M^{2})^{\alpha _{q}}\) in our various generated sets of hydro data.

Data Availability Statement
This manuscript has no associated data or the data will not be deposited. [Authors’ comment: Unlike UrQMD, hybrid UrQMD-hydro model is not an open access code. Moreover, all necessary information about the data have already been provided in the manuscript in the form of table and figures and thus there is no need of providing raw data as such.]
