| dc.description | We study the tetraquark state with I^G J^{PC} = 0^+ 1^{-+} in the QCD sum rule. We exhaust all possible flavor structures by using a diquark-antidiquark construction and find that the flavor structure 3*6+6*3 is preferred. There are altogether four independent currents which have the quark contents q s \bar q \bar s. By using both the Shifman-Vainshtein-Zakharov (SVZ) sum rule and the finite energy sum rule, these currents lead to mass estimates around 1.8 - 2.1 GeV, where the uncertainty is due to the mixing of two single currents. Its possible decay modes are S-wave b_1(1235) ηand b_1(1235) η^\prime, and P-wave KK, ηη, ηη^\prime and η^\prime η^\prime, etc. The decay width is around 150 MeV through a rough estimation. | |
