中文摘要: 随着高能物理实验的发展,对撞机能量和亮度以及测量精度不断提高,这使得理论计算需要考虑高阶修正的情况越来越多,而其计算的复杂和繁琐,迫使我们不得不借助计算机来进行。同时,在重夸克偶素领域,实验测量与理论预言之前的差距还在继续挑战我们对当前理论体系的理解。而随着Higgs粒子的发现,对Higgs性质的研究,以及新物理信号的寻找,已成为当前以及将来大型对撞机实验的重要目标。本项目的研究将针对这些问题,用微扰场论的方法,紧密结合实验进展,应用自动化计算系统FDC,对大型对撞机上相关物理问题进行研究,给出科学的理论预言,与实验进行比对或者为实验提供指引。在研究过程中将继续对FDC进行发展和完善,以保证满足不同物理问题的研究需求。本项目对检验和发展标准模型、深化人们对微观世界的结构及基本规律的认识有重要意义。

英文摘要: As the development of high energy experiment, the luminosity and energy of colliders, as well as the accuracy of the measurement have been gradually improved. This make it more and more important to include higher order corrections in theoretical predictions. But the complexity and difficulty make it necessary to do the the calculations with the help of computers. Meanwhile, in heavy quarkonium physics, the discrepancies between experiment measurements and theoretical predictions are still challenging our current understanding. On the other hand, after the discovery of higgs boson, the study on the properties of higgs boson and the search for new physics, have been the main targets of current and future large colliders. In this project, we will focus on above issues. Using perturbative field theory and tightly combined with latest experiment results, we will study on corresponding issues in large colliders with the help of automatic calculating system FDC. In the study, we will also improve and further develop FDC so that make it suitable for varies studies. This project will play an important role in examining and developing the Standard Model, and will deepen our current understanding of the basic law and structure of the microscopic world.
