Abstract

In these proceedings, we report the elliptic (v₂) and triangular (v₃) flow measurements of strange and multi-strange hadrons such as K_S⁰, ~Λ(Λ), ~ϕ, ~Ξ^-(Ξ⁺), and Ω^-(Ω⁺) at mid-rapidity (|y| < 1.0) in Au+Au collisions at √s_NN = 19.6 GeV using high statistics Beam Energy Scan Phase-II (BES-II) data. The transverse momentum (p_T) dependence, centrality dependence, and the number of constituent quarks (NCQ) scaling of v₂ and v₃ are studied for all these particles. A better NCQ scaling is observed in the case of antiparticles compared to particles, which can be attributed to the contribution from the transported quarks in particles. The hydrodynamically motivated ratio (v₃/v₂^3/2) is presented as a function of p_T.
