我们在解析QCD（量子色动力学）框架内研究π介子-光子跃迁形状因子，将实验数据与基于传统微扰理论及含“大质量”扭四贡献形式的解析微扰理论的微扰QCD进行对比。结果显示传统微扰理论无法重现实验数据，而解析版本与实验吻合良好。
英文摘要
We investigate the pion-photon transition form factor within the framework of analytic QCD. A comparison is performed between experimental data and perturbative QCD based on conventional and analytic versions of perturbation theory with the ``massive'' form of the twist-four contribution. We show that conventional perturbation theory fails to reproduce the data, while the analytic version demonstrates good agreement with experiment.
