Role of ${\Sigma }^{\ast }(1/2^{-})$ baryons in ${\Lambda }_c\to \Lambda {\pi }^{+}{\pi }^{+}{\pi }^{-}$ decay

Jun He

Based on Belle data, the structure around 1435 MeV and the role of the $\Sigma (1380)$ resonance in the decay process ${\Lambda }_c\to \Lambda {\pi }^{-}{\pi }^{+}{\pi }^{+}$ are investigated. The $\Lambda {\pi }^{\pm }$ invariant mass…
