New $\Omega_c^0$ baryons discovered by LHCb as the members of $1P$ and $2S$ states

Inspired by the recently observed Ωc0 states at LHCb, we decode their properties by performing an analysis of their mass spectrum and decay behavior. Our studies show that the five narrow states, i.e., Ωc(3000)0, Ωc(3050)0, Ωc(3066)0, Ωc(3090)0, and Ωc(3119)0, could be grouped into the 1P states with negative parity. Among them, the Ωc(3000)0 and Ωc(3090)0 states could be the JP=1/2- candidates, while Ωc(3050)0 and Ωc(3119)0 are suggested as the JP=3/2- states. Ωc(3066)0 could be regarded as a JP=5/2- state. Since the spin-parity, electromagnetic transitions, and possible hadronic decay channels Ωc(*)π have not been measured yet, other explanations are also probable for these narrow Ωc0 states. Additionally, we discuss the possibility of the broad structure Ωc(3188)0 as a 2S state with JP=1/2+ or JP=3/2+. In our scheme, Ωc(3119)0 cannot be a 2S candidate.
