研究方向:
粒子物理和量子场论,主要集中在微扰量子色动力学和重味物理领域。
主要学术成果:
1.完成了一系列的Bc介子及重夸克偶素产生碎裂函数(包括重夸克到Bc介子、胶子到Bc介子、重夸克到S波重夸克偶素、轻夸克到S波重夸克偶素的碎裂函数)的次领头阶修正计算。
2.对超级Z工厂(运行在Z共振峰附近的高亮度正负电子对撞机)上Bc介子及双重重子的产生过程进行了系统的理论研究。计算了超级Z工厂上Bc介子产生的次领头阶QCD修正效应,并结合碎裂函数方法对高阶微扰展开中出现的大对数项进行了重求和,得到了较之前文献更为精确的理论预言。
3.对高能对撞机上的一些重要的双重强子的间接产生过程(通过中间重粒子的衰变产生)进行了系统的研究。包括Higgs玻色子、Z玻色子、W玻色子、顶夸克衰变到Bc介子、双重重子等过程。
