- W2780743602 abstract "We have performed a theoretical study on the process ${ensuremath{chi}}_{c0}(1P)ensuremath{rightarrow}overline{mathrm{ensuremath{Lambda}}}mathrm{ensuremath{Sigma}}ensuremath{pi}$, by taking into account the final-state interactions of $ensuremath{pi}mathrm{ensuremath{Sigma}}$ and $ensuremath{pi}overline{mathrm{ensuremath{Lambda}}}$ based on the chiral unitary approach. As the isospin filters of $I=0$ in the $ensuremath{pi}mathrm{ensuremath{Sigma}}$ channel and $I=1$ in the $ensuremath{pi}overline{mathrm{ensuremath{Lambda}}}$ channel, this process can be used to study the molecular structure of the $mathrm{ensuremath{Lambda}}(1405)$ resonance and to test the existence of the predicted states $mathrm{ensuremath{Sigma}}(1380)$ and $mathrm{ensuremath{Sigma}}(1430)$ with spin parity ${J}^{P}=1/{2}^{ensuremath{-}}$. Our results show that there is a peak around 1350--1400 MeV and a cusp around the $overline{K}N$ threshold in the $ensuremath{pi}mathrm{ensuremath{Sigma}}$ invariant mass distribution, which should be the important feature of the molecular state $mathrm{ensuremath{Lambda}}(1405)$. We also find a peak around 1380 MeV and a cusp around the $overline{K}N$ threshold in the $ensuremath{pi}overline{mathrm{ensuremath{Lambda}}}$ invariant mass distribution, which are associated to the $mathrm{ensuremath{Sigma}}(1380)$ and $mathrm{ensuremath{Sigma}}(1430)$ resonances." @default.
