Description

We perform a systematic analysis of the low-lying Ωc structures in a coupled-channel approach of different structures, compact 3-quark structures and extended hadronic molecule structures. Our coupled channel methods explains naturally the observed Ωc's by LHCb including a threshold enhancement and a broad bump in the higher energy region.
