Effective theories of electroweak symmetry breaking

TL;DR

This paper reviews recent effective theories modeling electroweak symmetry breaking in extensions of the Standard Model, emphasizing Higgsless models and their analogy to Chiral Perturbation Theory, to understand strongly interacting dynamics at TeV scales.

Contribution

It provides a concise overview of effective theories for electroweak symmetry breaking, highlighting the connection to low-energy QCD analogies and Higgsless models.

Findings

Higgsless models can be described using effective theories similar to Chiral Perturbation Theory.

These theories offer insights into strongly interacting dynamics at TeV energy scales.

The review clarifies the theoretical framework for extensions of the Standard Model without a Higgs boson.

Abstract

We present a brief review of recent attempts to construct effective theories to describe the breaking of the electroweak symmetry in extensions of the Standard Model with new strongly interacting dynamics around the TeV scale. Particular attention is devoted to the analogies of Higgsless models with Chiral Perturbation Theory (the low-energy limit of QCD).
