在这篇文章,我们测试 X (3872 ) 的性质,它被假定是 P 波浪[cq ]-scalar-diquark [] 有 JP = 的 -axial-vector-antidiquark tetraquark 状态 2。代表 2 说的 JP = 的插入内推的水流被建议。技术上,直到尺寸六的操作员的贡献在操作员产品扩大被包括。为如此的状态获得的团是 m2 =(4.38 慥獲Ф
In this article, we test the nature of X(3872), which is assumed to be a P-wave [cq]-scalar-diquark [cq]- axial-vector-antidiquark tetraquark state with JP = 2^-. The interpolating current representing the JP = 2^- state is proposed. Technically, contributions of the operators up to dimension six are included in the operator product expansion. The mass obtained for such state is m2- = (4.38±0.15) GeV. We conclude that it is impossible to describe the X(3872) structure as JV = 2^- tetraauark state.
