Description
We present recent studies of strange baryons and their interactions, with a particular focus on the nature of the $\Lambda(1405)$ and on precision aspects relevant for future Lattice QCD calculations. We report updated results for the $\Lambda(1405)$, a long-standing candidate for a dynamically generated state arising from meson-baryon interactions. Using temporal correlation functions constructed from both single- and multi-hadron interpolating operators and employing the Lüscher formalism, we investigate the finite-volume spectrum and the associated coupled-channel scattering amplitudes. Additionally, we present ongoing work on scale setting using the $\Omega$ baryon, including strong-isospin-breaking and electromagnetic effects. This study aims at improving the determination of the lattice scale and thereby reducing one of the dominant sources of systematic uncertainty in precision Lattice QCD calculations.
