基于非相对论量子色动力学有效场论（NRQCD），项目将做以下三个方面的研究：.（1）项目将计算P波重夸克偶素电磁产生形状因子的两圈图修正，研究其辐射修正展开的收敛性，并在不同标度处给出高精度的理论预言。项目还将结合未来的CEPC和ILC做一些唯象分析和讨论。.（2）研究S波重夸克偶素ηc单举衰变到轻强子过程的两圈图修正，从而检验NRQCD因子化定理的正确性，并研究此过程辐射修正的收敛性、标度依赖性，以及结合实验做深入的唯象分析和讨论。.（3）项目将研究重夸克偶素电磁产生过程的次次领头阶形式因子在转移能量很大时（s→∞）的大对数项贡献，并与光锥因子化的预言作比较，从而检验光锥因子化的正确性。

Based on NRQCD, this project will study the following three important processes:.(1) We will calculate the two loop correction to the form factor of chi_J electromagnetic production, study the convergence of the radiative correction, and present the high accuracy theoretical predictions, which will be tested in the future CEPC and ILC colliders. .(2) The project will calculate the two loop correction to the ηc inclusive decay, discuss the convergence as well as the scale dependence of the radiative expansion, and make some phenomenological analysis in comparing theoretical prediction with experimental measurement. .(3) We will study the large logarithm terms from the two loop correction to the heavy quarkonium electromagnetic production in high energy, and test the prediction from light-cone factorization.
