Abstract
In this article, we study the axial-vector tetraquark state and two-quark-tetraquark mixed state consist of light quarks using the QCD sum rules. The present predictions disfavor assigning the as the axial-vector tetraquark state with , while support assigning the as the axial-vector two-quark-tetraquark mixed state.
