Elliptic Flow for {phi} Mesons and (Anti)deuterons in Au+Au Collisions at {radical}(s{sub NN})=200 GeV

Differential elliptic flow (v{sub 2}) for {phi} mesons and (anti)deuterons (d)d is measured for Au+Au collisions at {radical}(s{sub NN})=200 GeV. The v{sub 2} for {phi} mesons follows the trend of lighter {pi}{sup {+-}} and K{sup {+-}} mesons, suggesting that ordinary hadrons interacting with standard hadronic cross sections are not the primary driver for elliptic flow development. The v{sub 2} values for (d)d suggest that elliptic flow is additive for composite particles. This further validation of the universal scaling of v{sub 2} per constituent quark for baryons and mesons suggests that partonic collectivity dominates the transverse expansion dynamics.
