Theoretical interpretation of the $$\Xi (1620)$$ Ξ ( 1620 ) and $$\Xi (1690)$$ Ξ ( 1690 ) resonances seen in $$\Xi _c^+ \rightarrow \Xi ^- \pi ^+ \pi ^+$$ Ξ c + → Ξ - π + π + decay

Abstract We study the Belle reaction $$\Xi _c^+ \rightarrow \Xi ^- \pi ^+ \pi ^+$$ Ξ c + → Ξ - π + π + looking at the mass distribution of $$\pi ^+ \Xi $$ π + Ξ , where clear signals for the $$\Xi (1620)$$ Ξ ( 1620 ) and $$\Xi (1690)$$ Ξ ( 1690 ) resonances are seen. These two resonances are generat...
