Description
The study of flow harmonics provides valuable insights into the dynamics and properties of the Quark-Gluon Plasma (QGP) medium produced in heavy-ion collisions. The directed flow ($v_{1}$) slope ($dv_{1}/dy$) of protons at mid-rapidity is expected to be sensitive to the first-order phase transition. The number of constituent quark (NCQ) scaling of elliptic flow ($v_{2}$) can be regarded as a signature of the formation of QGP. Triangular flow ($v_{3}$) typically originates from fluctuations and is expected to provide constraints on the initial state geometry and fluctuations.
In this talk, we focus on the results of collective flow from Au+Au collisions at the top RHIC energy ($\sqrt{s_{NN}} =$ 200 GeV), the Beam Energy Scan (BES) program ($\sqrt{s_{NN}} =$ 3.0 to 27 GeV). Additionally, we will present results from the data collected for the deformed nuclei, such as Isobars (Ru+Ru and Zr+Zr) and U+U collisions. The transverse momentum ($p_{T}$), rapidity ($y$), and centrality dependence of $v_{1}$ and $v_{2}$ will be presented. Furthermore, the beam energy dependence of the $v_{1}$ and $v_{3}$ slopes and the $p_{T}$-integrated $v_{2}$ will be examined. The experimental results will be compared with model calculations to better understand the underlying physics mechanisms in heavy-ion collisions.
