$\Sigma (1385)$ results with STAR.

This paper introduces the Solenoidal Tracker experiment at the Relativistic Heavy Ion Collider. The corrected p _T spectra and the yields of the $\Sigma (1385)^{\pm}$ and their antiparticles in the most central Au + Au and elementary p + p collisions are presented. Comparison of the $\Sigma (1385)$ $\langle p_{T} \rangle$ measurement with the other particles corroborates the fact that the $\langle p_{T} \rangle$ behavior for hyperons (mass> 1.2 GeV) is similar in p + p and Au + Au collisions. The $\Sigma (1385)/\Lambda$ ratio, along with other resonance-to-stable-particle ratios, suggests that a regeneration mechanism recovers the signal loss due to re-scattering in the final state in Au + Au collisions.
