Abstract

The ∑(1385) analysis and the current status of pentaquark search with the STAR detector are reported. The corrected pT spectra and the yields of the ∑±(1385) and their antiparticles in the most central Au+Au as well as elementary p+p collisions are presented. A comparison of the 〈pT〉 of observed particles suggests a similar behaviour 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.
