We present high precision measurements of elliptic flow near midrapidity (|y| < 1.0) for multistrange hadrons and ϕ meson as a function of centrality and transverse momentum in Au + Au collisions at center of mass energy √^s_NN = 200  GeV. We observe that the transverse momentum dependence of ϕ and Ω υ₂ is similar to that of π and p, respectively, which may indicate that the heavier strange quark flows as strongly as the lighter up and down quarks. This observation constitutes a clear piece of evidence for the development of partonic collectivity in heavy-ion collisions at the top …
