Constraining the Chiral Magnetic Effect in the heavy-ion collisions using AVFD model (2502.01195v2)

Abstract: The Anomalous Viscous Fluid Dynamics (AVFD) framework is utilized to generate $^{197}{79}Au+^{197}{79}Au$, $^{96}{44}Ru+^{96}{44}Ru$, and $^{96}{40}Zr+^{96}{40}Zr$ collision events at $\sqrt{s_{\mathrm{NN}}}$ = 200 GeV to investigate the Chiral Magnetic Effect (CME). The CME signal is modulated through the axial charge per entropy density ($n_5/s$) in each event to produce data sets with varying CME signal strengths. Additionally, a 33$\%$ local charge conservation (LCC) is implemented in each event. These data sets are analyzed using CME-sensitive two- and three-particle correlators. Furthermore, the Sliding Dumbbell Method (SDM) is employed to identify potential CME-like events within each data set. The identified events selected using the SDM exhibit characteristics consistent with CME. The CME fraction in these events is quantified while accounting for background contributions.
