英文摘要: In this work we study the interaction of the coupled channels Omega eta and Xi*(K) over bar within the chiral unitary approach. The systems under consideration have total isospins 0, strangeness S = -3, and spin 3/2. We study the s wave interaction which implies that the possible resonances generated in the system can have spin-parity JP = 3/2. The unitary amplitudes in coupled channels develop poles that can be associated with some known baryonic resonances. We find there is a dynamically generated 3/2(-) Omega state with mass around 1800 MeV, which is in agreement with the predictions of the five-quark model.
