Abstract：
The standard model effective field theory (SMEFT) provides systematic parameterization of all possible new physics above the electroweak scale. I will describe a general procedure to construct the independent and complete operator basis up to any mass dimension. Given the complete set of operators, the next question would be how to find all possible UV origins of them. This can be done with the construction of the j-basis, corresponding to obtaining complete UV resonances in the bottom-up EFT paradigm, which provides a clear and effective pathway to new physics.

Jiang-Hao Yu, professor at Institute of Theoretical Physics, Chinese Academy of Science (ITP-CAS). He obtained Ph.D. at Michigan State University on 2012, and then worked as postdoc researcher at University of Texas at Austin and University of Massachusetts at Amherst before he held a position at ITP-CAS at 2017. His research area is theoretical particle physics and particle cosmology, focusing on effective field theory framework, origin of Higgs boson and neutrino masses, matter-antimatter asymmetry, neutrino and dark matter cosmology.
