Unnatural Origin of Fermion Masses for Technicolor

TL;DR

This paper investigates a hybrid model combining a dynamical sector and an elementary Higgs to explain electroweak symmetry breaking, constrained by experimental tests, and finds it to be a viable scenario.

Contribution

It introduces a low energy effective Lagrangian for a hybrid electroweak symmetry breaking model and constrains its parameters with experimental data.

Findings

The model is consistent with current experimental constraints.

The interplay of dynamical sector and elementary Higgs can produce viable electroweak symmetry breaking.

The proposed scenario is a plausible alternative to purely dynamical or elementary Higgs models.

Abstract

We explore the scenario in which the breaking of the electroweak symmetry is due to the simultaneous presence and interplay of a dynamical sector and an unnatural elementary Higgs. We introduce a low energy effective Lagrangian and constrain the various couplings via direct search limits and electroweak and flavor precision tests. We find that the model we study is a viable model of dynamical breaking of the electroweak symmetry.
