The $p_{\rm T}$-differential production cross section of inclusive $\rm \Omega_c^0$ baryons multiplied by the branching ratio into $\rm \Omega^-\pi^+$ for $|y|<0.5$ in pp collisions at $\sqrt{s}=13$ TeV. The error bars and empty boxes represent the statistical and systematic uncertainties, respectively. The measurement is compared with PYTHIA 8.243 with Monash tune  and with CR beyond the leading-colour approximation , which are multiplied by a theoretical $\rm BR(\Omega_c^0\rightarrow\Omega^-\pi^+)=(0.51^{+2.19}_{-0.31})\%$ .
