Minimal Flavor Constraints for Technicolor

TL;DR

This paper investigates how flavor observables constrain the properties of lightest spin-one resonances in models of dynamical electroweak symmetry breaking, impacting their self-couplings and masses.

Contribution

It provides a general analysis of flavor constraints applicable to a broad class of dynamical electroweak symmetry breaking models, including extra-dimensional extensions.

Findings

Strong constraints on resonance self-couplings

Significant bounds on resonance masses

Applicable to higher-dimensional models

Abstract

We analyze the constraints on the the vacuum polarization of the standard model gauge bosons from a minimal set of flavor observables valid for a general class of models of dynamical electroweak symmetry breaking. We will show that the constraints have a strong impact on the self-coupling and masses of the lightest spin-one resonances. Our analysis is applicable to any four and higher dimensional extension of the standard model reducing to models of dynamical electroweak symmetry breaking.
