Title: Elliptic Flow for phi Mesons and (anti)Deuterons in Au+Au Collisions at sqrt(s_NN) = 200 GeV

Abstract

Differential elliptic flow (v{sub 2}) for {phi} mesons and (anti)deuterons ({bar 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 ({bar 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.
