QCD sum rule studies on the $$s s {\bar{s}} {\bar{s}}$$ sss¯s¯ tetraquark states of $$J^{PC} = 0^{-+}$$ JPC=0-+
Abstract We apply the method of QCD sum rules to study the $$s s {\bar{s}} {\bar{s}}$$ sss¯s¯ tetraquark states of $$J^{PC} = 0^{-+}$$ JPC=0-+ . We construct all the relevant $$s s {\bar{s}} {\bar{s}}$$ sss¯s¯ tetraquark currents, and find that there are only two independent ones. We use them to fur...
