SMEFTsim 3.0 -- a practical guide

Understand

The SMEFTsim package is designed to enable automated computations in the Standard Model Effective Field Theory (SMEFT), where the SM Lagrangian is extended with a complete basis of dimension six operators.

• It contains a set of models written in FeynRules and pre-exported to the UFO format, for usage within Monte Carlo event generators.
• The models differ in the flavor assumptions and in the input parameters chosen for the electroweak sector.
• The present document provides a self-contained, pedagogical reference that collects all the theoretical and technical aspects relevant to the use of SMEFTsim and it documents the release of version 3.0.
