Description

Multistrangeness baryons ($S < -1$) are important in our understanding of strong interactions and are expected to be observed more precisely in the future experiments, e.g., J-PARC, FAIR/GSI, and JLab. We investigate the reaction mechanism of $K^- p \to K \Xi$ based on the effective Lagrangian approach. In addition to the usual Born diagrams, the box diagrams are taken into account in detail. We find that a few $\Lambda^*$ and $\Sigma^*$ resonances are crucial in explaining the recent J-PARC data.
