Study of charmoniumlike and fully-charm tetraquark spectroscopy

The masses of tetraquark states all $qc\overline{q}\overline{c}$ and $cc\overline{c}\overline{c}$ quark configurations are evaluated in a constituent model, where the Cornell-like potential one-gluon exchange spin-spin coupling employed. All model parameters predetermined by comparing theoretical experimental light, charmed bottom mesons. predictions charmoniumlike tetraquarks compared with observed $XYZ$ states, one tentative assignment is suggested. work suggests that $X(6900)$ LHCb likely to be first radial excited fully-charm state ${J}^{PC}={1}^{+\ensuremath{-}}$ ${\overline{3}}_{c}\ensuremath{\bigotimes}{3}_{c}$ configuration, ground second around 6494 7253 MeV respectively.
