Analysis of the X(4475), X(4500), $$Z_{\bar{c}\bar{s}}(4600)$$ Z c ¯ s ¯ ( 4600 ) , and related tetraquark states with the QCD sum rules
Abstract In this work, we introduce an explicit P-wave to construct the diquarks $$[qc]_{\widehat{V}}$$ [ q c ] V ^ , then construct the local four-quark currents to explore the hidden-charm tetraquark states with the $$J^{PC}=0^{++}$$ J PC = 0 + + , $$1^{+-}$$ 1 + - , and $$2^{++}$$ 2 + + in the fr...
