Resonance Production in Heavy Ion Collisions: Suppression of $\mathrm{\Lambda }(1520)$ and Enhancement of $\mathrm{\Sigma }(1385)$

We investigate the yield of $\mathrm{\Lambda }(1520)$ 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 $\Lambda(1520)+\pi \leftrightarrow \Sigma^$canfavor$\Sigma^$ production, thereby decreasing the $\mathrm{\Lambda }(1520)$ yield. Within the same approach we thus find a yield enhancement for $\mathrm{\Sigma }(1385)$ and a yield suppression for $\mathrm{\Lambda }(1520)$.
