NLO Standard model effective field theory for Higgs and EW precision data

TL;DR

This paper provides a systematic framework for the Standard Model Effective Field Theory (SMEFT), focusing on how high-energy processes influence Higgs and electroweak precision data through a limited set of parameters.

Contribution

It introduces a structured approach to SMEFT, clarifying how higher energy effects can be encapsulated by Wilson coefficients for Higgs and electroweak observables.

Findings

Defines key constructs and propositions for SMEFT

Shows how higher energy influences are captured by Wilson coefficients

Provides a systematic methodology for analyzing Higgs and EW data

Abstract

A set of constructs, definitions, and propositions that present a systematic view of the Standard Model Effective Field Theory (SMEFT), i.e. how the influence of higher energy processes is localizable in a few structural properties which can be captured by a handful of Wilson coefficients.
