$\Gamma_{1}$ ${{\mathit \Lambda}_{{{c}}}{(2595)}^{+}}$ $\rightarrow$ ${{\mathit \Lambda}_{{{c}}}^{+}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ ($4.0$ $\pm1.4$) $ \times 10^{-1}$ 117
Note: See AALTONEN 2011H, Fig. 8, for the calculated ratio of ${{\mathit \Lambda}_{{{c}}}^{+}}{{\mathit \pi}^{0}}{{\mathit \pi}^{0}}$ and ${{\mathit \Lambda}_{{{c}}}^{+}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ partial widths as a function of the ${{\mathit \Lambda}_{{{c}}}{(2595)}^{+}}$ $−$ ${{\mathit \Lambda}_{{{c}}}^{+}}$ mass difference. At our value of the mass difference, the predicted ratio is about$~$4. Using the measured value of ${{\mathit \Lambda}_{{{c}}}^{+}}{{\mathit \pi}^{0}}{{\mathit \pi}^{0}}$ branching fraction and assuming the ${{\mathit \Lambda}_{{{c}}}}{{\mathit \pi}}{{\mathit \pi}}$ branching fractions sum to unity, we derive the ${{\mathit \Lambda}_{{{c}}}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ branching fraction. The derived ratio of the ${{\mathit \Lambda}_{{{c}}}}{{\mathit \pi}^{0}}{{\mathit \pi}^{0}}$ to ${{\mathit \Lambda}_{{{c}}}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ partial widths is correspondingly $1.5$ $\pm0.2$.
