This paper extends an earlier one describing the Higgs boson $H$ as a light composite scalar in a strong extended technicolor model of electroweak symmetry breaking. The Higgs mass $M_H$ is made much smaller than $\Lambda_{ETC}$ by tuning…

In multiscale and topcolor-assisted models of walking technicolor, relatively light spin-one technihadrons $\rho_T$ and $\omega_T$ exist and are expected to decay as $\rho_T \to W \pi_T, Z \pi_T$ and $\omega_T \to \gamma \pi_T$. For…

The recently discovered resonance at 125 GeV has properties remarkably close to those of the Standard Model Higgs boson. We perform model-independent fits of all presently available data. The non- standard best-fits found in our previous…
