EWSB from strongly-coupled dynamics: an EFT approach and implications for WW production

TL;DR

This paper discusses how strongly-coupled dynamics behind electroweak symmetry breaking (EWSB) can be modeled using effective field theory, focusing on systematic power-counting, operator basis, and implications for WW production at colliders.

Contribution

It develops a consistent EFT framework for strongly-coupled EWSB, including power-counting and NLO operators, with applications to WW production processes.

Findings

Established a systematic power-counting formula.

Constructed the basis of next-to-leading order operators.

Analyzed implications for WW production at colliders.

Abstract

If the dynamics behind EWSB are of strongly-coupled nature, the Standard Model ceases to be renormalizable and should be instead understood as an effective field theory (EFT). Here I will discuss the systematics behind this effective field theory description. My focus will be on deriving a consistent power-counting formula and building the basis of NLO operators. As an application, I will consider WW production both at linear and hadron colliders.
