Belle II
The Belle experiment has been integral in conducting measurements through the decay of various baryons, including Λ, Ξc0 , Ξc+ , and Ωc but only a handful have undergone a full amplitude analysis. The amplitude analysis is critical as it allows us to dissect and interpret the underlying processes and structures in these decays. An amplitude analysis of Ξc0 decays has the potential to expose the presence of new states and measure their quantum numbers and other properties. Some recent studies have shown the existence of Ξ(1690) and Ξ(1620) in Ξc+ decays and Λ+c decays. This Ξc0 → Λ0 K− π+ decay mode includes potential resonant substructure including Ξ(1690)− and Ξ(1820)− along with some well-known resonances like K∗(892) and Σ(1385). I will present an ongoing amplitude analysis on Ξc0 → Λ0 K− π+ to measure the branching fraction and spin-parity of resonant substructures using Belle II simulations.
