任哲,博士毕业于中国科学院理论物理研究所,现在在西班牙格拉纳达大学做博士后。主要研究方向是超出标准模型的新物理,尤其是标准模型有效场论,和用有限温有效场论的方法研究电弱相变。

报告简介:

The Standard Model Effective Field Theory (SMEFT) provides a systematic framework for parameterizing heavy new physics in a model-independent way. We compute the one-loop running of dimension-eight two-fermion operators induced by pairs of dimension-six terms and dimension-eight terms in the SMEFT. The calculation is performed off shell, for which we obtain and provide a new and explicitly Hermitian basis of dimension-eight Green' s functions. The analysis involves a large set of redundant operators, introducing significant technical complexity and making the computation error-prone. We overcome the difficulty by utilizing various SMEFT tools, especially the Amplitude Basis Construction for Effective Field Theories (ABC4EFT).
