轴向载体Charmonia $χ_{c1}(1P)$和$χ_{c1}(2P)$的研究

J. Y. Süngü, A. C. Jumasahatov

摘要:

研究了基态重夸克偶素$χ_{c1}(1P)$及其第一激发态$χ_{c1}(2P)$,量子数为$J^{PC}=1^{++}$。用两点QCD求和规则方法计算了这些粲偶素态的质量和衰变常数,包括夸克、胶子和混合凝聚到8维。我们比较我们的数值计算结果与现有的实验数据以及文献中的理论预测。

英文摘要:

We investigate the ground-state heavy quarkonium $χ_{c1}(1P)$ and its first excited state $χ_{c1}(2P)$ with quantum numbers $J^{PC}=1^{++}$. The masses and decay constants of these charmonium states are computed using two-point QCD sum rule method by including quark, gluon and mixed condensates up to dimension-8. We compare our numerical results with the available experimental data as well as existing theoretical predictions in the literature.
