Description
In this contribution, we investigate the nature of the $\Sigma^*(1430)$ resonance recently observed by the Belle Collaboration, which is interpreted as a dynamically generated state from the $\bar K N$ interaction in coupled channels within the chiral unitary approach. From a molecular perspective of $\Sigma^*(1430)$, we study its production in the $\Lambda_c^+ \to \Lambda \pi^+ \pi^+ \pi^-$ decay via a triangle singularity mechanism, and estimate the branching ratio for $\Lambda_c^+ \to \pi^+ \pi^- \Sigma^*(1430)$. In addition, we calculate the correlation functions for the $\bar{K}^0 p, \pi^+ \Sigma^0, \pi^0 \Sigma^+, \pi^+ \Lambda$, and $\eta \Sigma^+$ channels, and tackle the inverse problem of seeing how much information one can extracted from these correlation functions.
