Descrição: This paper introduces the Solenoidal Tracker experiment at the Relativistic Heavy Ion Collider. The corrected pT 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.
