Elliptic flow of charged hadrons in d + Au collisions at [Formula presented] GeV using a multiphase transport model

This study presents a comprehensive analysis of the elliptic flow coefficient, v2, for charged hadrons at midrapidity in d + Au collisions at [Formula presented] GeV. Utilizing a multiphase transport (AMPT) model in both default and string melting modes, we examine the dependence of v2 on transverse momentum, collision centrality, and particle type. Furthermore, we present v2 across different collision centralities in d + Au collisions at [Formula presented] GeV within the AMPT model with the string melting mode. Our results indicate that the early-stage partonic phase significantly influences v2, as observed by variations in parton scattering cross section. We also studied the effect of final-state hadronic interactions on v2 by varying the hadronic cascading time. Comparisons with STAR and PHENIX experimental data show that the AMPT model effectively captures the transverse momentum dependence of v2, underlining the importance of parton scattering mechanisms and the need for careful interpretation of experimental results in asymmetric systems.
