On the search for the two poles of the $$\Xi (1820)$$ Ξ ( 1820 ) in the $$\psi (3686) \rightarrow \bar{\Xi }^+ \bar{K}^0 \Sigma ^{*-}(\pi ^- \Lambda )$$ ψ ( 3686 ) → Ξ ¯ + K ¯ 0 Σ ∗ - ( π - Λ ) decay
Abstract We propose the reaction $$\psi (3686) \rightarrow \bar{\Xi }^+ \bar{K}^0 \Sigma ^{*-}$$ ψ ( 3686 ) → Ξ ¯ + K ¯ 0 Σ ∗ - , with the $$\Sigma ^{*-}$$ Σ ∗ - decaying to $$\pi ^- \Lambda $$ π - Λ in order to show evidence for the existence of two $$\Xi (1820)$$ Ξ ( 1820 ) states, one around 1824...
