Excited c baryons as 2S states
Abstract
The LHCb experiment has recently reported two excited c resonances decaying to c+ K-, with masses about 3185 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.
