The ${\Omega }_{cc}$ resonances with negative parity in the chiral constituent quark model

Abstract

Spectrum of the low-lying ${\Omega }_{cc}$ resonances with negative parity, which are assumed to be dominated by $sccq\bar{q}$ 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 Goldstone boson. Possible $sccq\bar{q}$ 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 $4050\pm 100$ 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 $\bar{D}{\Xi }_c$ channel by future experiments.
