Excited ωc Baryons as 2S states

Marek Karliner, Jonathan L. Rosner

Research output: Contribution to journalArticlepeer-review


The LHCb experiment has recently reported two excited ωc resonances decaying to Ξc+K-, with masses about 3185 MeV and 3327 MeV. We discuss their assignment to 2S1/2 and 2S3/2 states, which can be compared with masses based on extrapolation from the observed 1S states. The agreement is not perfect, but weighs against an earlier alternative assignment. Consequences for the spin-averaged 2P states are discussed.
