Transverse Dynamics at RHIC

Studies of <p_{T}>, transverse momentum spectra and anisotropy flow from nuclear collisions at RHIC indicate early thermalization and strong collective expansion. We propose a systematic study of the anisotropy parameter $v_2$ and the transverse momentum distributions of $\varphi ,\mathrm{\Omega },D^0,{\mathrm{\Lambda }}_C$ and $J / \psi$ in order to extract information on partonic collective flow.
