Lowest vector tetraquark states: Y(4260 / 4220) or $$Z_c(4100)$$ Zc(4100)
Abstract In this article, we take the Y(4260 / 4220) as the vector tetraquark state with $$J^{PC}=1^{--}$$ JPC=1-- , and construct the $$C\gamma _5\otimes {\mathop {\partial }\limits ^{\leftrightarrow }}_\mu \otimes \gamma _5C$$ Cγ5⊗∂↔μ⊗γ5C type diquark-antidiquark current to study its mass and pole...
