  The production of Lambda(1520) in p+p and Au+Au collisions provided by the
RHIC at sqrt{s_NN}=200 GeV are investigated using the STAR detector. A
preliminary Sigma(1385) signal is also shown. Models predict that a late
rescattering phase in ultra-relativistic heavy ion collisions should lower the
measured yields of these resonances. This reduction is presently confirmed
through the Lambda(1520)/Lambda ratio which has been calculated for p+p
collisions and compared with Au+Au collisions.
