报告摘要：

We compute the two-loop Higgs plus three partons amplitudes with high dimensional operators in Higgs effective theory. This provides the two-loop S-matrix elements for the top mass corrections for Higgs plus a jet production at LHC. The results take remarkably simple analytic form. In particular, the maximally transcendental part (functionally the most complex part) presents hidden relations and universal structure. In this talk, I will give an introduction to the related background and also explain the method used to obtain the results.

Gang Yang received his Bachelor degree from Shanghai Jiao Tong University in 2004. He got his PhD in 2009 from Institute of Theoretical Physics, Chinese Academy of Sciences (ITP-CAS). After that, he became a Research Associate at Queen Mary College, University of London, and later also at University of Hamburg and Humboldt University of Berlin. In 2016 he joined ITP-CAS as an Associated Professor. He received the National Science Fund for Excellent Young Scholars in 2018. His research area is quantum field theory (QFT) and string theory, and his recent interests are high-loop amplitudes in QFT and their analytic structures.
