  Inspired by the discovery of the dibaryon $d^{*}$ and the experimental search
of $N\Omega$ dibaryon with the STAR data, we study the strange dibaryon
$N\Omega$ further in the framework of quark delocalization color screening
model and chiral quark model. We have shown $N\Omega$ is a narrow resonance in
$\Lambda\Xi$ D-wave scattering before. However, the $\Lambda$-$\Xi$ scattering
data analysis is quite complicated. Here we calculate the low-energy $N\Omega$
scattering phase shifts, scattering length, effective range and binding energy
to provide another approach of STAR data analysis. Our results show there
exists an $N\Omega$ "bound" state, which can be observed by the $N$-$\Omega$
correlation analysis with RHIC and LHC data, or by the new developed automatic
scanning system at J-PARC. Besides, we also find that the hidden color
channel-coupling is important for the $N\Omega$ system to develop
intermediate-range attraction.
