摘要Here we investigate mixing of the low-lying three- and five-quark Omega states with spin-parity quantum numbers 1/2(-) and 3/2(-), employing the quark-antiquark creation triggered by Nambu-Jona-Lasinio (NJL) interaction. Wave functions of the three- and five-quark configurations are constructed by using the extended constituent quark model, within which the hyperfine interaction between quarks is also taken to be the NJL-induced one. Numerical results show that the NJL-interaction-induced pair creation results in vanishing mixing between three- and five- quark Omega configurations with spin- parity 1/2(-), but mixing between three- and five-quark 3/2 Omega states should be very strong. The mixing decreases energy of the lowest 3/2(-)Omega state to be 1785 +/- 25 MeV, which is lower than energy of the lowest 1/2(-) state in this model. This is consistent with our previous predictions within the instanton-induced quark-antiquark creation model.
