Contrasting observables related to the $N^{*} (1535)$ from the molecular or a genuine structure

Hai-Peng Li, Jing Song, Wei-Hong Liang +2

In this work we compare the predictions for the scattering length and effective range of the channels $K^{0} Σ^{+}, K^{+} Σ^{0}, K^{+} Λ$ and $η p$ , assuming the $N^{*} (1535)$ state as a molec…

Theoretical interpretation of the $Ξ (1620)$ and $Ξ (1690)$ resonances seen in $Ξ_{c}^{+} \to Ξ^{-} π^{+} π^{+}$ decay

Hai-Peng Li, Gong-Jie Zhang, Wei-Hong Liang +1

We study the Belle reaction $Ξ_{c}^{+} \to Ξ^{-} π^{+} π^{+}$ looking at the mass distribution of $π^{+} Ξ$ , where clear signals for the $Ξ (1620)$ and $Ξ (1690)$ resonances are seen. These two…
