Possible interpretation of the newly observed state
Abstract
Inspired by the newly observed $Ω (2012)$ state at Belle II, we investigate the two-body strong decays of $Ω$ baryons up to $N = 2$ shell within the chiral quark model. Our results indicate that (i) the newly observed $Ω (2012)$ state could be assigned to the spin-parity $J^P = 3 / 2^-$ state |$$70,^{2}10, 1, 1, \frac{3^-}{2}$$$\rangle$$ and the experimental data can be reasonably described. However, the spin-parity $J^P = 1 / 2^-$ state |$$70,^{2}10, 1, 1, \frac{1^-}{2}$$$\rangle$$ and spin-parity $J^P = 3 / 2^+$ state |$$56, ^{4}10, 2, 0, \frac{3^+}{2}$$$\rangle$$ cannot be completely excluded. (ii) The $D$-wave states in the $N = 2$ shell are most likely to be narrow states with a width of dozens of MeV and have a good potential to be observed in the $$\Xi$$K$ and/or $$\Xi(1530)K$$ channels in future experiments. The $Ω(2250)$ resonance listed in PDG may be a good candidate for the $J^P$ = $5/2^+$ $1D$ wave state |$56$,$$^{4}10$$, $2, 2$, $5/2^+$ $$\rangle$$ .
