论文摘要
利用稳定标准内的两点相关器的QCD表达式中现有的QCD表达式中的QCD表达式（LSR），我们对B_C样量表（0^{++}）的光谱和衰减常数进行了首次分析媒介媒介。通过将这些LSR结果与重型夸克对称性（HQS）相结合的一些质量分布来获得改进的预测。我们通过重新访问B^*_ {0}（0^{++}）质量来完成分析，该质量可能可以用B^*_ J（5732）实验候选者识别。将表2中收集的光谱的结果与一些最近的晶格和潜在模型的结果进行了比较。表3给出了衰减常数的新估计。
Using the existing state of art of the QCD expressions of the two-point correlators into the Inverse Laplace sum rules (LSR) within stability criteria, we present a first analysis of the spectra and decay constants of B_c-like scalar (0^{++}) and axial-vector (1^{++}) mesons and revisit the ones of the B^*_c(1^{--}) vector meson. Improved predictions are obtained by combining these LSR results with the some mass-splittings from Heavy Quark Symmetry (HQS). We complete the analysis by revisiting the B^*_{0}(0^{++}) mass which might be likely identified with the B^*_J(5732) experimental candidate. The results for the spectra collected in Table 2 are compared with some recent lattice and potential models ones. New estimates of the decay constants are given in Table 3.
