Description
The Relativistic Heavy-Ion Collider aims to study the deconfined state of quarks and gluons known as Quark-Gluon Plasma and its transition from hadronic matter. $\phi$($s\bar s$) meson has a small hadronic cross-section implying lesser final state interactions in the medium. Thus, the elliptic flow ($v_{2}$) of $\phi$ mesons is sensitive to the properties of the medium in the initial stages of heavy-ion collisions. The $v_{2}$ of $\phi$ mesons hints at being lower than that of the other hadrons and deviates drastically from the number of constituent quark scaling below the center-of-mass energy of 19.6 GeV obtained in the first phase of Beam Energy Scan (BES-I) program indicating a difference in dynamics of the medium. Triangular flow ($v_{3}$), originating from initial geometry fluctuations, is suggested to be an even more sensitive probe for the viscosity of the medium and initial density profile of the colliding nuclei. Further, the ratios of higher-order flow harmonics are suggested to depend on the transport properties of the medium. \
In this poster, we will present $v_{2}$($p_{T}$) and $v_{3}$($p_{T}$) of $\phi$ mesons and their ratio in Au+Au collisions at $\sqrt{s_{\mathrm {NN}}}$ = 14.6 and 19.6~GeV from the second phase of Beam Energy Scan (BES-II) program. The centrality and energy dependence of the observables will be presented. The new results shall also be compared with the previous results from BES-I.
