Abstract
Very recently LHCb reported the evidence of a new charged charmoniumlike structure in the invariant mass spectrum near 4600 MeV. In this work we investigate this structure together with three other charged charmoniumlike states, the , , and . Our results suggest that the two higher states can be established as the first radial excitations of the two lower ones, all of which have the quantum numbers . We propose to search for more connections among exotic hadrons in order to better understand them.
