  "abstract": "We study the $$J/\\psi \\rightarrow \\Lambda \\pi \\bar{\\Sigma }$$ J / ψ → Λ π Σ ¯ reaction by looking at the $$\\pi ^+ \\Lambda $$ π + Λ mass distribution at low energies, in search of signals for the low lying $$\\Sigma ^*$$ Σ ∗ excited states. Apart from a clear signal of the $$\\Sigma (1385) (3/2^+)$$ Σ ( 1385 ) ( 3 / 2 + ) state, we find a smaller peak for the predicted $$\\Sigma (1430) (1/2^-)$$ Σ ( 1430 ) ( 1 / 2 - ) , which has already been confirmed by the Belle Collaboration. A first analysis, considering only the $$\\pi \\Lambda $$ π Λ interaction, shows that the low energy part of the spectrum is better reproduced including contributions from the $$\\Sigma (1430)$$ Σ ( 1430 ) and the predicted $$\\Sigma (1380)(1/2^-)$$ Σ ( 1380 ) ( 1 / 2 - ) state that has been claimed before from analyses of different experiments. However, when we consider the $$\\pi \\bar{\\Sigma }$$ π Σ ¯ interaction the need for the $$\\Sigma (1380)$$ Σ ( 1380 ) disappears.",
