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

Abstract

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