Hidden charm tetraquark states in a diquark model

The purpose of the present study is to explore mass spectrum hidden charm tetraquark states within a diquark model. Proposing that state composed and an antidiquark, masses all possible $[qc][\overline{q}\overline{c}]$, $[sc][\overline{s}\overline{c}]$, $[qc][\overline{s}\overline{c}]$ $([sc][\overline{q}\overline{c}])$ are systematically calculated by use effective Hamiltonian, which contains color, spin, flavor dependent interactions. Apart from $X(3872)$, $Z(3900)$, ${\ensuremath{\chi}}_{c2}(3930)$, $X(4350)$ taken as input fix model parameters, results support ${\ensuremath{\chi}}_{c0}(3860)$, $X(4020)$, $X(4050)$ $[qc][\overline{q}\overline{c}]$ with ${I}^{G}{J}^{PC}={0}^{+}{0}^{++}$, ${1}^{+}{1}^{+\ensuremath{-}}$, ${1}^{\ensuremath{-}}{2}^{++}$, respectively, ${\ensuremath{\chi}}_{c1}(4274)$ $[sc][\overline{s}\overline{c}]$ ${I}^{G}{J}^{PC}={0}^{+}{1}^{++}$, $X(3940)$ ${I}^{G}{J}^{PC}={1}^{\ensuremath{-}}{0}^{++}$ or ${1}^{\ensuremath{-}}{1}^{++}$, ${Z}_{cs}(3985{)}^{\ensuremath{-}}$ $[sc][\overline{q}\overline{c}]$ ${J}^{P}={0}^{+}$ ${1}^{+}$, ${Z}_{cs}(4000{)}^{+}$ ${Z}_{cs}(4220{)}^{+}$ ${J}^{P}={1}^{+}$. Predictions for other also given.
