Searching for New Physics using Precision Standard Model Measurements

Abstract

New physics interactions beyond the Standard Model can make themselves known as small corrections to Standard Model reactions. There is a diverse array of proposals for new physics, and so any parametrization of those effects must be as general and all-inclusive as possible. This can be accomplished by the use of Standard Model Effective Field Theory (SMEFT). In this article, part of the celebration of 50 years of the Standard Model of particle physics, I describe how SMEFT has been applied to search for new physics in fermion-fermion scattering and precision electroweak analysis and how it will be applied in the precision study of the Higgs boson.
