The explanation of some exotic states in the $$cs{\bar{c}}{\bar{s}}$$ tetraquark system

Inspired by the recent observation of $\chi_{c0}(3930)$, $X(4685)$ and $X(4630)$ LHCb Collaboration some exotic resonances such as $X(4350)$, $X(4500)$, etc. several experiment collaborations, $cs\bar{c}\bar{s}$ tetraquark systems with $IJ^{P}=00^+$, $01^+$ $02^+$ are systematically investigated in framework quark delocalization color screening model(QDCSM). Two structures, meson-meson diquark-antidiquark well channel-coupling all channels these two configurations considered this work. The numerical results indicate that molecular bound state $\bar{D}_{s}D_{s}$ $IJ^{P}=00^+$ can be supposed to explain $\chi_{c0}(3930)$. Besides, using stabilization method, resonant states obtained. There four $IJ^{P}=00^{+}$ around resonance mass 4035 MeV, 4385 4524 4632 respectively; one $IJ^{P}=01^{+}$ 4327 MeV; $IJ^{P}=02^{+}$ 4419 MeV 4526 respectively. All them compact tetraquarks. Among states, $X(4500)$ $X(4700)$ explained $IJ^{P}=00^{+}$, $X(4274)$ is possible a candidate $IJ^{P}=01^{+}$. More experimental tests expected check existence states.
