光阵面夸克模型中赝标跃迁形状因子的研究

Study of pesudoscalar transition form factors within light front quark model

Chao-Qiang Geng, Chong-Chung Lih

摘要:

本文在光阵面夸克模型中研究了赝标量介子($π,η$和$η^{\prime}$)的跃迁形状因子随动量转移$Q^2$的变化。我们比较了我们的结果与CELLO,CLEO,BaBar和Belle最近的实验数据。通过考虑夸克质量可能带来的不确定性,我们说明了我们预测的形状因子可以与所有的数据拟合,包括在大$Q^2$区域的数据。

英文摘要:

We study the transition form factors of the pesudoscalar mesons ($π,η$ and $η^{\prime}$) as functions of the momentum transfer $Q^2$ within the light-front quark model. We compare our results with the recent experimental data by CELLO, CLEO, BaBar and Belle. By considering the possible uncertainties from the quark masses, we illustrate that our predicted form factors can fit with all the data, including those at the large $Q^2$ regions.
