Query: Resonance Production in Au+Au and p+p Collisions at $\sqrt{s_{NN}} = $
  200 GeV   The $\rho^0(770)$, $K^{*0}(892)$, $f_{0}(980)$, $\phi(1020)$, and
$\Lambda(1520)$ production in Au+Au and p+p collisions at $\sqrt{s_{_{NN}}} = $
200 GeV are presented. These resonances are used as a sensitive tool to examine
the collision dynamics in the hadronic medium through their decay and
regeneration. The modification of resonance mass, width, and shape due to phase
space and dynamical effects are also discussed.
