报告摘要:The standard model (SM) effective field theory (EFT) is a powerful approach to searching for deviations from the SM, where predictions can be systematically improved in precision. I will discuss some recent progresses and on-going efforts in developing the SM EFT to next-to-leading order (NLO) accuracy, in particular in the top-quark sector. Based on the MadGraph5_aMC@NLO framework, one can now start from an EFT with top-quark operators, and make NLO predictions for various processes, for cross sections as well as distributions, in a fully automatic way. Furthermore, NLO results matched to the parton shower simulation become available, allowing for event generation to be directly employed in an experimental analyses. These works provide a solid basis for the interpretation of current and future measurements in the EFT framework, with improved accuracy and precision. Future developments and perspectives will also be discussed.
