Description

We investigate the yield of Λ(1520) resonance in heavy ion collisions within the framework of a kinetic master equation without the assumption of chemical equilibrium. We show that reactions such as Λ(1520)+π↔Σ* can favor Σ* production, thereby decreasing the Λ(1520) yield. Within the same approach we thus find a yield enhancement for Σ(1385) and a yield suppression for Λ(1520)
