Study on the $Ω_{c}^{0}$ States Decaying to $Ξ_{c}^{+}K^{-}$ in $pp$ collisions at $\sqrt{s}=7$, 13 TeV

Abstract: The production of strange particles $\Xi_{c}^{+}, K<sup>{-}$ is simulated in mid-rapidity $pp$ collisions at $\sqrt{s}=7$ TeV with $0.2 \leq pt \leq 6$~GeV/c using the {\footnotesize PACIAE} model. The results are consistent with LHCb experimental data on $\Xi_{c}<sup>{+}$ and $K<sup>{-}$ yield. Then, a dynamically constrained phase-space coalescence ({\footnotesize DCPC}) model plus {\footnotesize PACIAE} model was used to produce the $\Xi_{c}<sup>{+}K<sup>{-}$ bound states and study the narrow excited $\Omega_{c}<sup>{0}$ states through $$\Omega_{c}^{0} \to \Xi_{c}<sup>{+}K<sup>{-}$$ in $pp$ collisions at $\sqrt{s}=7$ and 13 TeV. The yield, transverse momentum distribution, and rapidity distribution of the five new excited $\Omega_{c}<sup>{0}$ states of $\Omega_{c}(3000)<sup>{0}$, $\Omega_{c}(3050)<sup>{0}$, $\Omega_{c}(3066)<sup>{0}$,$\Omega_{c}(3090)<sup>{0}$and $\Omega_{c}(3119)<sup>{0}$ were predicted.
