The production of strange particles ${\mathrm{\ensuremath{\Xi}}}_{c}^{+},{K}^{\ensuremath{-}}$ is simulated in $pp$ collisions at $\sqrt{s}=7$ TeV at mid-rapidity with $0.2\ensuremath{\le}{p}_{T}\ensuremath{\le}6$ $\mathrm{GeV}/c$ using the paciae model. The results are consistent with LHCb experimental data on ${\mathrm{\ensuremath{\Xi}}}_{c}^{+}$ and ${K}^{\ensuremath{-}}$ yield. Then, a dynamically constrained phase-space coalescence model plus paciae model was used to produce the ${\mathrm{\ensuremath{\Xi}}}_{c}^{+}{K}^{\ensuremath{-}}$ bound states and study the narrow excited ${\mathrm{\ensuremath{\Omega}}}_{c}^{0}$ states through ${\mathrm{\ensuremath{\Omega}}}_{c}^{0}\ensuremath{\rightarrow}{\mathrm{\ensuremath{\Xi}}}_{c}^{+}{K}^{\ensuremath{-}}$ in $pp$ collisions at $\sqrt{s}=7$ and 13 TeV. The yield, transverse momentum distribution, and rapidity distribution of the five new excited ${\mathrm{\ensuremath{\Omega}}}_{c}^{0}$ states of ${\mathrm{\ensuremath{\Omega}}}_{c}{(3000)}^{0}$, ${\mathrm{\ensuremath{\Omega}}}_{c}{(3050)}^{0}$, ${\mathrm{\ensuremath{\Omega}}}_{c}{(3066)}^{0}$, ${\mathrm{\ensuremath{\Omega}}}_{c}{(3090)}^{0}$, and ${\mathrm{\ensuremath{\Omega}}}_{c}{(3119)}^{0}$ were predicted.
