Description
A $\Sigma^*$ resonance with spin-parity $J^P = 1/2^−$ and mass in the vicinity of the $\bar{K}N$ threshold has been predicted in the five quark ficture and the unitary chiral approach. In this talk, based on the dominant Cabibbo favored weak decay mechanism, we perform a study of $\Lambda^+_c$ decays for studying the possible $\Sigma^*$ state decaying into $\pi \Lambda$ or $\pi \Sigma$. We show that these $\Lambda^+_c$ decays can be used to study the possible $\Sigma^*$ state.
