Abstract
This note gives an overview of the tools for predicting expectations in the Standard Model effective field theory (SMEFT) at the tree level and one loop available through event generators. Methods of event reweighting, the separate simulation of squared matrix elements, and the simulation of the full SMEFT process are compared in terms of statistical efficacy and potential biases.
Author comments upon resubmission
We thank the referees for the thoughtful comments, which we have addressed and documented in the files attached to each comment's reply.
List of changes
*) WZ: Fixed a bug effecting events with large EFT weights, improving the consistency of the predictions
*) VBF-H: Fixed scale choice, improving the consistency of the predictions
*) Added representative Feynman diagrams for all processes
*) Improved the clarity of the text in many places
