Initial large global angular momentum in non-central relativistic heavy-ion collisions can produce strong vorticity, and through the spin-orbit coupling, causes the spin of particles to align with the system’s global angular momentum. We present the azimuthal angle dependent (relative to the reaction plane) polarization for Λ and Λ in mid-central Au+Au collisions at [see formula in PDF] = 200 GeV. We also present the ϕ meson spin alignment parameter, ρ00 in Au+Au collisions at [see formula in PDF] = 19.6, 27, 39, 62.4 and 200 GeV. The implications of the results are discussed.
