A methodology for theory uncertainties in the SMEFT

Abstract

A process specific methodology is defined to systematically assign theoretical uncertainties in the Standard Model Effective Field Theory when performing leading order global fits. The method outlined also minimises the computational and theoretical burden to systematically advance such analyses to dimension eight.
