WW Scattering in Walking Technicolor

TL;DR

This paper investigates WW scattering in walking technicolor models, showing that certain parameter regions delay unitarity violation up to 3-4 TeV without requiring light resonances, consistent with electroweak data.

Contribution

It demonstrates that walking technicolor models can naturally delay unitarity violation without sub-TeV resonances, aligning with electroweak precision constraints.

Findings

Unitarity violation delayed to 3-4 TeV in certain parameter regions.

Allowed parameter space consistent with electroweak precision data.

No need for sub-TeV resonances to maintain unitarity.

Abstract

We analyze the WW scattering in scenarios of dynamical electroweak symmetry breaking of walking technicolor type. We show that in these theories there are regions of the parameters space allowed by the electroweak precision data, in which unitarity violation is delayed at tree level up to around 3-4 TeV without the inclusion of any sub-TeV resonances.
