Description
SMEFT provides systematical parametrization of all possible new physics at electroweak scale. It is quite challenge to write down independent higher dimensional operators due to derivatives and repeated fields. In this talk, I present a systematical and unified construction of Lorentz, gauge, and flavor structures using Young tensor, which solves difficulties from equation of motion, integration by part and spin-statistics, and connects possible UV physics. This method could be generalized to any Lorentz invariant EFT with any gauge symmetry up to any mass dimension. 个人简介:于江浩,中国科学院理论物理研究所研究员、博士生导师,2012年在密歇根州立大学获博士学位,先后在得克萨斯大学奥斯汀和麻省大学阿姆斯特分校从事博士后研究,2017年底起先后任职理论所副研究员和研究员,获基金委优青资助。研究领域为粒子物理和粒子宇宙学,近期研究集中于Higgs质量起源和电弱相变,标准模型有效场论,重子轻子生成及低能检验,暗物质中微子宇宙学。 Online Tencent/VOOV meeting: https://meeting.tencent.com/s/86s9hzOIrnIf 会议 ID:949 166 570
