Description

The Jülich-Bonn model is a well-established dynamical coupled-channel approach that has been applied in recent years primarily to study the spectrum of light baryon resonances from pion- and photon-induced reactions with different hadronic final states. In this talk, I will present the adaptation of the framework to kaon-induced reactions with the goal to extract the spectrum of resonances with strangeness S=-1, i.e. $\Lambda^*$ and $\Sigma^*$ states. Resonance parameters in terms of pole positions and residues are determined from simultaneous fits to experimental data for the reactions $\bar K N\to \pi\Lambda$, $\pi\Sigma$ and $\bar K N$.
I will compare our results to other recent studies and briefly discuss opportunities for new data and their potential to improve our knowledge of the spectrum of strange resonances.
