Sigma(1385) Results and Status of the Theta^{+} in STAR

Abstract

The Sigma(1385) analysis and the current status of pentaquark search with the STAR detector are reported. The corrected p_{T} spectra and the yields of the Sigma ^{\pm}(1385) and their antiparticles in the most central Au+Au as well as elementary p+p collisions are presented. A comparison of the <p_{T}> of observed particles suggests a similar behavior for particles with mass greater than 1.2 GeV in p+p and Au+Au collision environments. Acceptance and efficiency studies with simulations show that the (anti)pentaquarks should be found at the 3% level.
