S-通道单胶子交换作用下可能分子态X(3872)的动力学研究

Dynamical study of the possible molecular state X(3872) with the s-channel one gluon exchange interaction

Bao-Kai Wang, Xiao-Lin Chen, Wei-Zhen Deng

摘要:

最近观察到的X(3872)共振,在夸克模型中很难被归属为传统的$c\bar{c}$粲偶素态,但可以解释为分子态。这种分子态是一种隐味的四夸克态,因为它具有类似粲的量子数。s通道单胶子交换是一种只作用于隐味多夸克系统的相互作用。本文在考虑s通道单胶子交换作用的夸克模型中研究了X(3872)和其它类似的隐味分子态。

英文摘要:

The recently observed X(3872) resonance, which is difficult to be assigned a conventional $c\bar{c}$ charmonium state in the quark model, may be interpreted as a molecular state. Such a molecular state is a hidden flavor four quark state because of its charmonium-like quantum numbers. The s-channel one gluon exchange is an interaction which only acts in the hidden flavor multi-quark system. In this paper, we will study the X(3872) and other similiar hidden flavor molecular states in a quark model by taking into account of the s-channel one gluon exchange interaction.
