Abstract

In this article, we study the axialvector-diquark-axialvector-antidiquark type scalar, axialvector, tensor, and vector ss�s�s tetraquark
states with the QCD sum rules. The predicted mass mX = 2:08 ± 0:12 GeV for the axialvector tetraquark state is in excellent
agreement with the experimental value ð2062:8 ± 13:1±4:2Þ MeV from the BESIII collaboration and supports assigning the
new X state to be a ss�s�s tetraquark state with JPC = 1+−. The predicted mass mX = 3:08 ± 0:11 GeV disfavors assigning ϕð2170Þ
or Yð2175Þ to be the vector partner of the new X state. As a byproduct, we obtain the masses of the corresponding qq�q�q
tetraquark states. The light tetraquark states lie in the region about 2 GeV rather than 1 GeV
