We study the mass spectra of the $N\Omega$ dibaryons in the $^{3}S_1$ and$^{5}S_2$ channels with $J^{P}=1^{+}$ and $2^{+}$ respectively, by using themethod of QCD sum rules. We construct two dibaryon interpolating currents inthe molecular picture and calculate their correlation functions and spectraldensities up to dimension-16 condensates. Our results indicate that there mayexist an $N\Omega$ dibaryon bound state in the $^{5}S_2$ channel with a bindingenergy of about $21\ \mathrm{MeV}$. The masses of the $^{3}S_1$ $N\Omega$dibaryons with $J^{P}=1^{+}$ are predicted to be higher than the $N\Omega$ and$\Lambda\Xi$ thresholds, and thus can decay into these final states directly inS-wave. The $N\Omega (^{5}S_2)$ dibaryon bound state can decay into theoctet-octet final states $\Lambda\Xi$ and $\Sigma\Xi$ in D-wave via the quarkrearrangement mechanism. The existence of these $N\Omega$ dibaryons may beidentified in the relativistic heavy-ion collision experiments in the future.
