Excited Ωc Baryons as 2 S states

The LHCb experiment has recently reported two excited Ω_c resonances decaying to Ξ_c⁺K^- , with masses about 3185 MeV and 3327 MeV. We discuss their assignment to 2 S_{1 /2} and 2 S_{3 /2} states, which can be compared with masses based on extrapolation from the observed 1 S states. The agreement is not perfect, but weighs against an earlier alternative assignment. Consequences for the spin-averaged 2 P states are discussed.
