Abstract

In this proceedings, we have presented the invariant yield measurements of strange and multi strange hadrons such as K⁰_S, Λ, Λ, ϕ, Ξ^-, Ξ⁺, Ω^-, Ω⁺ in Au+Au collisions at √s_NN = 54.4 GeV at midrapidity (|y|<0.5). The second and third-order azimuthal anisotropic flow of the above mentioned particles at √s_NN = 27 and 54.4 GeV are also discussed. Some of the important observables such as nuclear modification factor (R_CP), baryon to meson ratio (Ω/ϕ), transverse momentum dependence of v₂ and v₃ are measured. The number of constituent quark (NCQ) scaling of v₂ and v₃ is studied for all these particles.
