Elliptic flow and Number of Constituent Quarks scaling provide crucial insights into the underlying dynamics and degrees of freedom in heavy-ion collisions. This article provides some insights on the transition from hadronic to partonic collectivity, revealing possible key signatures of medium evolution. At low energies around (√s\rm NN ≤ 4.0 GeV), v2 may be negative and NCQ scaling might break down. We expect that as the collision energy rises beyond 4.0 GeV, v2 may become positive and NCQ scaling gradually restores. The transition in v2 behavior, coupled with the breakdown and restoration of NCQ scaling, highlights the increasing significance of partonic interactions at higher energies, marking the onset of partonic collectivity and the emergence of quark-gluon plasma (QGP)-like properties.
