We investigate the yield of ≈(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 ≈(1520)+a σ* can favor σ* production, thereby decreasing the ≈(1520) yield. Within the same approach we thus find a yield enhancement for σ(1385) and a yield suppression for ≈(1520).
