1  From a fit in the region $\mathit M_{ {{\mathit p}} {{\overline{\mathit \Lambda}}} }−\mathit M_{{{\mathit p}}}−\mathit M_{{{\mathit \Lambda}}}$ $<$ 150 MeV. ${\mathit S}{\mathrm -wave}$ in the ${{\mathit p}}{{\overline{\mathit \Lambda}}}$ system preferred. A similar near-threshold enhancement in the ${{\mathit p}}{{\overline{\mathit \Lambda}}}$ system is observed in ${{\mathit B}^{+}}$ $\rightarrow$ ${{\mathit p}}{{\overline{\mathit \Lambda}}}{{\overline{\mathit D}}^{0}}$ by CHEN 2011F.
