排除$X(3940)$的$c\bar c$解释

Exclusion of $c\bar c$ Interpretation for $X(3940)$

W. Sreethawong, K. Xu, Y. Yan

摘要:

在$^3P_0$夸克模型中计算了$X(3940)$的部分衰变宽度,并假设其结构为粲偶素。在研究中,所有模型参数都是由其他反应预先确定的。结果表明,在势夸克模型加$^3P_0$夸克动力学的图象中,很难将$X(3940)$与任何$c\bar c$介子态相适应.

英文摘要:

Partial decay widths of the $X(3940)$ are evaluated in the $^3P_0$ quark model, assuming a charmonium scenario for its structure. In the study all model parameters are predetermined by other reactions. The work reveals that it is difficult to accommodate the $X(3940)$ with any $c\bar c$ meson state in the picture of the potential quark model plus the $^3P_0$ quark dynamics.
