Analysis of the $$QQ\bar{Q}\bar{Q}$$ Q Q Q ¯ Q ¯ tetraquark states with QCD sum rules
Abstract In this article, we study the $$J^{PC}=0^{++}$$ J P C = 0 + + and $$2^{++}$$ 2 + + $$QQ\bar{Q}\bar{Q}$$ Q Q Q ¯ Q ¯ tetraquark states with the QCD sum rules, and we obtain the predictions $$M_{X(cc\bar{c}\bar{c},0^{++})} =5.99\pm 0.08\,\mathrm {GeV}$$ M X ( c c c ¯ c ¯ , 0 + + ) = 5.99 ± 0....
