报告题目： Effective Operator Bases for Standard Model and Gravity

报告摘要： Effective field theories provide systematical parametrization on new physics beyond the standard model and Einstein's gravity.  It is quite challenging to write independent higher dimensional operators due to higher 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. Based on spacetime and internal symmetries, we explore operator bases in various effective theories and their possible ultraviolet completions.
