摘要:

采用双夸克-反双夸克内插流的两点求和规则方法计算了D 0合作组新观测到的$X(5568)$态的质量和衰变常数。在计算中,考虑了多达八个维度的真空冷凝物。对$X(5568)$态质量的计算结果与实验数据符合得很好。

英文摘要:

The mass and decay constant of the $X(5568)$ state newly observed by D0 Collaboration are computed within the two-point sum rule method using the diquark-antidiquark interpolating current. In calculations, the vacuum condensates up to eight dimensions are taken into account. The obtained result for the mass of the $X(5568)$ state is in a nice agreement with the experimental data.
