摘要：
The production of strange particles Xi(+)(c), K- is simulated in pp collisions at root s = 7 TeV at mid-rapidity with 0.2 <= P-T <= 6 GeV/c using the PACIAE model. The results are consistent with LHCb experimental data on Xi(+)(c) and K- yield. Then, a dynamically constrained phase-space coalescence model plus PACIAE model was used to produce the Xi K-+(c)- bound states and study the narrow excited Omega(0)(c) states through Omega(0)(c) -> Xi K-+(c)- in pp collisions at root s = 7 and 13 TeV. The yield, transverse momentum distribution, and rapidity distribution of the five new excited Omega(0)(c) 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.
