Mass-Spectroscopy of Hidden Charm and Hidden Strange Tetraquarks in Diquark-Antidiquark Approach

We investigated the four-quark systems with quark structures of $$cs\bar{c}\bar{s}$$ , $$cq\bar{c}\bar{s}$$ $$bs\bar{b}\bar{s}$$ and $$bq\bar{b}\bar{s}$$ in framework non-relativistic model, motivated by recent observation exotic resonances X(4140), X(4274), X(4350), X(4500), X(4700) reported several experiment collaborations. The colour antitriplet-triplet configuration diquark-antidiquark combinations all conceivable quantum numbers have been used to calculate their masses. results reveal that if structure is $$\bar{3}_{c} \otimes 3$$ tetraquarks may occur otherwise observed as resonance. X(4274) state, can be defined $$J^{PC}=2^{++}$$ tetraquark while X(4140) state regarded $$J^{PC}=1^{++}$$ this calculation. When radial excitation considered, explained a 2 S excited $$J^{PC}=0^{++}$$ . orbitally states Y(4626), Y(4630) Y(4660) P-wave number $$1^{{-}{-}}$$ masses [ ] are found range between 10.5 11.5 GeV very close two-meson thresholds.
