Mid-rapidity φ production in Au+Au collisions at image GeV Original Research Article

Measurements of mid-rapidity φ vector meson production in Au+Au collisions at RHIC (View the MathML source GeV) from the STAR detector are described. By measuring the φ → K+K− decay channel, we have successfully reconstructed φ mesons at mid-rapidity from 0.5 < pt < 3.8 GeV/c. We observe no strong centrality dependence of the exponential slope parameter, T. Finally, we present the first measurement of the azimuthal anisotropy (v2) for the φ meson in minimum-bias collisions.
