Mass spectrum of the axial-vector hidden charmed and hidden bottom tetraquark states

Abstract

In this article, we perform a systematic study of the mass spectrum of the axial-vector hidden charmed and hidden bottom tetraquark states using the QCD sum rules, and identify the $Z^{+}(4430)$ as an axial-vector tetraquark state tentatively.
