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…

Two states for the $Ξ (1820)$ resonance

R. Molina, Wei-Hong Liang, Chu-Wen Xiao +2

We recall that the chiral unitary approach for the interaction of pseudoscalar mesons with the baryons of the decuplet predicts two states for the $Ξ (1820)$ resonance, one with a n…
