Three-body hadronic structure of low-lying $1/2^{+}$ $\Sigma$ and $\Lambda$ resonances

A. Martínez Torres, K. P. Khemchandani, E. Oset

We discuss the dynamical generation of some low-lying $1/2^{+}$ $\Sigma$'s and $\Lambda$'s in two-meson one-baryon systems. These systems have been constructed by adding a pion in $S$-wave to t…
