This note gives an overview of the tools for the precision matching of ultraviolet theories to the Standard Model effective field theory (SMEFT) at the tree level and one loop. Several semi- and fully automated codes are presented, as well as some supplementary codes for the basis conversion and the subsequent running and matching at low energies. [...]

LHC EFT WG Report: Experimental Measurements and Observables / Castro, Nuno (LIP - Laboratorio de Instrumentação e Física Experimental de Partículas (PT)) ; Cranmer, Kyle Stuart (New York University (US)) ; Gritsan, Andrei (Johns Hopkins University (US)) ; Howarth, James William (University of Glasgow (GB)) ; Magni, Giacomo (Nikhef) ; Mimasu, Ken (King's College London) ; Rojo Chacon, Juan (CERN) ; Roskes, Jeffrey (Johns Hopkins University (US)) ; Vryonidou, Eleni (University of Manchester (GB)) ; You, Tiann-Tevong (CERN)
The LHC effective field theory working group gathers members of the LHC experiments and the theory community to provide a framework for the interpretation of LHC data in the context of EFT. In this note we discuss experimental observables and corresponding measurements in analysis of the Higgs, top, and electroweak data at the LHC [...]
