CAS Key Laboratory of Theoretical Physics | Institute of Theoretical Physics | Chinese Academy of Sciences | Seminar | Title 题目 | Yang-Mills Theory in the CHY Formalism | Speaker 报告人 | | Affiliation 所在单位 | | Date 日期 | 2:30pm, May 29, 2019, Wednesday | | | Venue 地点 | ITP South (New) Building 6420 | Abstract 摘要 | n-gluon tree diagrams can be formally expressed as a Mobius-invariant integral over (n-3) complex variables. In order for this CHY formalism to describe the complete Yang-Mills theory, a similar formula must be found for off-shell gluons, namely, all tree-level Green's functions in momentum space. This is a non-trivial task because space-time local interaction and its propagation, as well as local gauge invariance demanded by the Yang-Mills theory, must be directly incorporated into a Mobius-invariant integral of momenta and polarization. I will discuss how this can be done. | Contact Person 所内联系人 | Song He | |
