英文摘要	Spectrum of the low-lying Omega(cc) resonances with negative parity, which are assumed to be dominated by sccq (q) over bar pentaquark components, is investigated using the chiral constituent quark model. Energies of the Omega(cc) resonances are obtained by considering the hyperfine interaction between quarks by exchanging a Goldstone boson. Possible sccq (q) over bar configurations with spin-parity 1/2(-), 3/2(-), and 5/2(-) are taken into account. Numerical results show that the lowest Omega(cc) resonances with negative parity may lie at 4050 +/- 100 MeV. In addition, the transitions of the Omega(cc) resonance to a pseudoscalar meson and a ground baryon state are also investigated within the chiral Lagrangian approach. We expect that these Omega(cc) resonances could be observed in the D Xi(c) channel by future experiments.
